Description du sujet

Title:  "Development of prescriptive analytics for energy systems"

 

Context and background:

Operational management of energy systems in time scales of a few minutes to days ahead involves decision making that results from two major steps: (1) leveraging contextual information to forecast uncertain input quantities like electricity demand, weather-dependent renewable production (wind, solar, hydro…), electricity market quantities (prices, imbalances…), and (2) optimization, where the forecasts are used as input to optimization tools for congestion management, economic dispatch, unit commitment, electricity trading, reserves estimation and other applications. The classical “Forecast then Optimise” approach may involve a complex model chain of multiple models that one has to tune and maintain. For example, when trading the production of a virtual power plant (VPP) in day ahead and ancillary service markets, one may need as many as 11 models (energy and market quantities forecasting and stochastic optimization). Further, forecast accuracy might not align with performance optimality. In the last years the new paradigm of “Prescriptive Analytics” emerged, where data-driven approaches integrated the two steps. For example, end-to-end machine learning (ML) models can be trained to minimize the downstream decisions regret or even directly learn a mapping from data to decisions. First works that focus on the energy trading model chain have shown that equivalent results can be obtained with the analytical approach.  This is a new and very promising field that needs to be further explored in different use cases and contexts.


Scientific objectives:

The overarching objective of this thesis is to develop and validate the prescriptive analytics approach in different use cases of the energy sector. The aim is to develop methods based on data-driven optimization and ML that improve decision quality and simplify complex model chains. The considered use cases can be the classical ones of predictive management of power systems but also applications that can be related to edge computing or even industrial processes. The application of prescriptive analytics at the “edge”, and especially at the consumers level (EVs, smart homes, smart buildings…), is promising since it permits to simplify the model chain at that level and thus to robustify and automatize the “intelligence” layer of applications at that level. In this context, it is also important to consider aspects such as the intepretability and explainability of decisions given the context, as well as to ensure that the algorithmic design permits implementation in micro-computers.


Methodology and expected results:


The methodological focus is on the edge of machine learning and mathematical programming. The first step will be to carry out a bibliographic research and familiarize with previous developments in this area in our Centre. These developments concern existing probabilistic forecasting methods for energy forecasting (demand, EVs demand, prices, renewable generation), as well as optimization algorithms for trading of VPPs, optimal power flow, congestion management, microgrids scheduling and other applications. PERSEE has developed first approaches for prescriptive analytics based on artificial neural networks and prescriptive decision trees focusing on the energy trading application. The aim is to propose generic solutions for a broad number of typical use cases and deal with requirements for adaptability/replicability, interpretability, feasibility of decisions, as well as privacy/confidentiality preservation when information/data is shared, automatization of the process, resilience on disruptive events, etc. An experimental implementation for such a typical use-case (i.e. energy community with smart homes or microgrid management) may be envisaged to demonstrate AI-based prescriptive solutions on the edge.

Présentation établissement et labo d'accueil

Mines Paris - PSL, Centre PERSEE

The PERSEE Center is one of the 18 research centers of MINES Paris. Its field of expertise concerns New Energy Technologies and Renewable Energy Sources (RES). Its research strategy is based on a "micro/macro" approach ranging from (nano)materials to energy systems. It is built around three structuring themes: i) materials and components for energy, ii) sustainable energy conversion and storage processes and technologies, and iii) renewable energies and smart energy systems.

This late is developped by one of the three groups of the Center, ERSEI, which stands for “Renewable Energies and Smart Energy Systems”. The ERSEI group develops methods and tools allowing the optimal integration of decentralized sources, including RES, storage devices, electric vehicles, active demand and other technologies, in energy systems and electricity markets. The research activity of the group is divided into three main themes. The first is based on the development of advanced short-term forecasting methods for different applications in power systems (i.e. forecasting of RES production, demand, dynamic line rating, market quantities, etc.). The second concerns the control and predictive management of energy systems. The aim is to design innovative approaches to optimise the operation (from real-time to days ahead) of different types of systems (smart-homes, microgrids, virtual power plants, energy communities, hybrid RES/storage plants, distribution grids multi-energy systems a.o.) considering uncertainties. The third axis concern planning and prospective studies that aim to optimise the design of future energy systems, generate furture scenarios, optimise investements etc.  

The PERSEE Center is located within the scientific parc of Sophia-Antipolis, near the cities of Nice, Cannes and Antibes in the south of France. Its workforce is around 50 people.
