ILUSTRE is a living lab in the Caribbean with the objective to develop, implement and test AI innovations that will accelerate the use of clean energy and advance solutions in water treatment and wastewater recycling/purification. The lab is a collaboration between JADS, the University of Curaçao, Lanubia Consulting, Aqualectra, WEB Bonaire, Alliander, KPN, CIWC, and the Ministry of Economic Development in Curaçao.

We expect recruitment for this lab to open in early 2023. Please check back frequently for updated information about how to apply, and to register for an online information session in February. If you’d like to join our mailing list, please fill out the form, and we will be happy to keep you informed of all the latest developments.

ILUSTRE offers opportunities for PhD candidates who wish to support the acceleration of the energy transition and who have an affinity with the Dutch Caribbean islands. The lab will house five PhD researchers who will work simultaneously on different aspects of the overall applied aim to create accurate and reliable AI solutions to improve the efficiency and effectiveness of water and energy distribution.

Curaçao has a modern National Energy Policy, which sets the objectives and priorities for the development of an effective and sustainable energy system with the goal to achieve 50% renewable energy penetration by 2030. Data technology will be an enabler for this objective which aligns with Curaçao’s ambition to become a smart country that embraces the development of data technology and Artificial Intelligence. Curaçao, therefore, welcomes this initiative of Jheronimus Academy of Data Science (JADS) and LaNubia Consulting.

The Five PhD researchers will be located at JADS and at the utility companies to preserve the academic environment and the transfer of domain-specific expertise, respectively. It is foreseen that the PhD researchers will reside at the utility companies at least once per year for an extended period of time to test their algorithms in real-life settings. To further the dissemination of the acquired knowledge and skills, we foresee short visits to Dutch (e.g. Alliander), European (e.g. E.ON), and other Caribbean (e.g. VEi) utility companies and consortia.

Sustainable Development Goals

ILUSTRE Lab is part of the ROBUST program on Trustworthy AIbased Systems for Sustainable Growth which is financed under the NWO LTP funding scheme. To accelerate the energy transition and ensure tangible social value, the lab will focus on four specific targets of Sustainable Development Goals (SDGs) 6 and 7.

SDG 6: Ensure availability and sustainable management of water and sanitation for all

Target 6.1: Achieve universal and equitable access to safe and affordable drinking water for all;
Target 6.2: Expand international cooperation and capacity-building support to developing countries in water- and sanitation-related activities and programs, including water harvesting, desalination, water efficiency, wastewater treatment, recycling, and reuse technologies.

SDG 7: Ensure access to affordable, reliable, sustainable, and modern energy for all

Target 7.1: Substantially increase the share of renewable energy in the overall energy mix;
Target 7.2: Achieve a smart power distribution grid that will eliminate power grid outages and reduce the overall production and distribution costs for energy.


Artificial Intelligence for decision support in water desalination, recycling, and purification

Scientific Challenge

For over 30 years, AI and computational intelligence have been used in the water desalination domain [1] for applications like support in decision-making, prediction, optimization, and control with respect to alarm processing, fault detection, load forecasting, and security assessment. The recent trend to use renewable energy sources for desalination and wastewater treatment makes the decision process more complicated, due to the temporal variability of these sources [2,3,4]. AI systems that go beyond the current point solutions are needed to deal with this complexity while considering a system-wide view and a balanced interaction between the AI systems and human experts. The scientific challenge of this PhD project is to develop hybrid AI solutions that combine advanced prediction methods (e.g. deep learning algorithms), multi-objective optimization, and adaptive models with explainable AI decision-making methods from computational intelligence to realize such a balance.


We will use attention-based deep learning techniques for predictive modeling and time series analysis (e.g. [5]) in combination with explainable/transparent deep models (e.g. [6]). The methods will be adaptive to deal with changing conditions and parameter drift (e.g. [7]). For addressing challenging dynamic optimization problems considering multiple perspectives, we will use multi-objective evolutionary computation extended with methods for dealing with soft constraints in such optimization challenges [8]. Probabilistic fuzzy systems [9] will be used for fusing information from multiple sources in a way consistent with models reflecting the experts’ knowledge and preferences. The models will be combined with data-driven process analytics [10] to provide solutions at the business process management level. From this basis, we will develop hybrid approaches that are tailored to the challenges of the desalination, recycling, and purification domain.

Artificial Intelligence for power load and renewable energy forecasting in electricity grids

Scientific challenge

Short-term forecasts of (a) power load and (b) renewable energy supply, are crucial for decarbonizing electricity grids: without these forecasts, high-carbon baseload generators must be kept running. The scientific challenge is to achieve accurate and reliable forecasts, in the face of changeable energy demand patterns and external covariates (weather, public events, etc). Deep learning has been shown to perform very well in power-load forecasting and achieves promising results in renewable-energy forecasting (Wang et al., 2019). This PhD plan sets out to develop deep learning algorithms that realize forecasts that are both accurate and reliable, with the flexibility to adapt to local conditions.


Time-series forecasting has a rich history: deep learning and Gaussian process regression are two modern paradigms that have shown strong performance, including for energy forecasting (Wang et al. 2019, [2]). We will build on both these paradigms, as well as on promising recent “neural process” models that may offer the best of both worlds. Power load(demand) and renewable energy supply can each be treated within the same framework, but each has different patterns and external covariates. External covariates can have rich features including graph-structured information to improve the accuracy of our predictions and account for power network efficiency losses [3]. We will explore the accuracy and reliability of the described methods for the two forecasting tasks, while iterating with the involved partners Aqualectra, WEB Bonaire, WEB Aruba, and GEBE Sint-Maarten to ensure that what is produced is relevant to deployment needs in Curacao and more broadly. At JADS we have the required expertise and deep learning and probabilistic models [4]. We also have experience applying such methods to the monitoring of critical assets and renewable energy forecasts [2,5,6].

Artificial Intelligence for predictive maintenance in water and electricity infrastructure

Scientific challenge

Predictive maintenance offers great potential value to the energy and water supply industry (cf. SDG7). Timely detection of required maintenance of machines, sensors, or other critical infrastructure can prevent disruptions of service and costly loss of resources. For instance, visual sensors can be used to analyze and detect subtle patterns [1,2,3] and auditory sensors can pick up subtle changes in sounds [4]. More generally, artificial intelligence offers improved prediction performance on predictive maintenance tasks. Recent advances in visual object recognition and auditory analysis allow for continuous and reliable monitoring of system states. In particular, the focus will be on self-supervised and unsupervised learning, see [5]. In the absence of supervisory labels, adequate priors will be acquired using large unlabeled datasets, see [6]. In the context of Industry 4.0, predictive maintenance leads to numerous innovations. One of the main challenges is dealing with real-time-based predictive maintenance [7]. Instead of treating predictive maintenance as simple alert monitoring, real-time-based predictive maintenance offers an estimate of time-to-failure.


Building on existing work [7] and our own expertise acquired in the NWO-funded CERTIF-AI project, we will explore unsupervised and self-supervised learning in traditional and generative neural networks to achieve real-time-based predictive maintenance algorithms. The accuracy and reliability of these algorithms will be studied for predictive maintenance of water and energy installations of Aqualectra, and of WEB Bonaire, WEB Aruba, and GEBE Sint-Maarten. Our collaboration with Alliander, E-ON, and KPN facilitates the integration of the electricity grid and telecom infrastructure.

AI for power grid balancing using recommendation-enhanced Demand Response

Scientific challenge

To improve grid balancing (SDG7), esp. in the case of many renewable energy resources and fluctuating demand, AI forecasting methods (WP2) can be combined with Demand Response (DR) methods. DR motivates energy consumers in some way (e.g. pricing-based) to adjust their energy usage to the available energy resources and demand. Smart grid technology allows DR to be more data-driven and a multitude of AI technologies have already been applied to DR [1], including ML, deep learning, and agent-based approaches. However, little research has investigated the consumer side of DR apart from simple customer segmentation approaches [1]. Rather than having consumers (household or industry) passively follow the DR (pricing) scheme, AI technology such as recommender algorithms could play an active role in recommending to consumers how and when to distribute their energy usage and return-based energy forecasts and DR information. Such tailored interventions improve DR approaches and optimize dynamic grid balancing.


In the field of energy advice, most advice is not tailored yet. Recommender technology offers the ability to tailor what actions to take and when. For example, energy recommendations can be more effective when tailored to the users’ ability [2,3] and should be contextualized, for example by using micro-moments [4]. However, these insights are from the domestic domain and have not been researched in a more industrial context. We will extend current AI energy consumption forecasting and DR methods with tailored and explainable recommendations that will provide both household and industry consumers with tailored advice on how to adjust for Demand Response. As many stakeholders are involved, and dynamic changes in energy usage will affect other consumers in the network, a multi-stakeholder perspective on recommendations should be employed [5].

Social support for the real-world introduction of AI in critical infrastructure

Scientific challenge

The social impact of technology on its users has been vastly proven to be enormous [1] since it might pose organizational and social obstacles. Acceptance of new technologies, especially in the energy field, has been recognized as one of the primary barriers to implementing technological innovations [2]. In the context of the ILUSTRE project, the impact of IT technology on the energy and water supply domains is twofold. First: the impact on the partners’ industry managers and employees. The implementation creates disruption, and unless managers support the innovation and workers understand and comply with the new infrastructure, they might actively oppose the implementation. Second: the impact on the broader society since AI technology will affect the quality and the features of the services provided to the population. The scientific challenge addressed in this Ph.D.-project is to employ group model building (GMB) and social network analysis (SNA) to monitor the extent to which the employees and the larger public (together called the stakeholders) receive and respond to the implementation. GMB is a widely used approach to collect data and monitor (and influence) the opinions and sentiments of groups of stakeholders [3]. SNA has been used extensively to analyze the group dynamics at the roots of technological implementation reception [4]. These techniques can well be used in conjunction with agent-based simulation models.


The research team will involve the stakeholders in GMB activities (such as one seminar per year, either online or in-person, where the researchers coordinate activities) with two main purposes: 1) collect relevant data about stakeholders’ opinions, demographics, and relationships, 2) increase the stakeholder involvement in the implementation and their perception of being an essential part of the process.
