Deep reinforcement learning approaches for the hydro-thermal economic dispatch problem considering the uncertainties of the context

Arango, A.R. (author), Aguilar, J. (author), R-Moreno, M.D. (author)

Hydro-thermal economic dispatch is a widely analyzed energy optimization problem, which seeks to make the best use of available energy resources to meet demand at minimum cost. This problem has great complexity in its solution due to the uncertainty of multiple parameters. In this paper, we view hydro-thermal economic dispatch as a multistage...

A Single-Level Rule-Based Model Predictive Control Approach for Energy Management of Grid-Connected Microgrids

Pippia, T. (author), Sijs, J. (author), de Schutter, B. (author)

A single-level rule-based model predictive control (RBMPC) scheme is presented for optimizing the energy management of a grid-connected microgrid composed of local production units, renewable energy sources, local loads, and several types of energy storage systems (ESSs). The single-level controller uses two different models that yield different...

Optimization of in-depth water diversion using a fully implicit thermal-compositional approach

Sangers, M. (author), Trujillo, R. (author), Voskov, D. (author), Leeuwenburgh, O. (author)

We investigate the potential for improved recovery of subsurface energy resources (hydrocarbons or heat) through in-depth diversion technology. A number of pilot studies in the North Sea have demonstrated in recent years that sodium silicate can be used to block preferential flow paths and divert water to previously unswept areas of a reservoir....

Validation of a robust neural real-time voltage estimator for active distribution grids on field data

Pertl, M. (author), Douglass, P.J. (author), Heussen, K. (author), Kok, J.K. (author)

The installation of measurements in distribution grids enables the development of data driven methods for the power system. However, these methods have to be validated in order to understand the limitations and capabilities for their use. This paper presents a systematic validation of a neural network approach for voltage estimation in active...

Integrating demand flexibility with distributed generation - Renewable energy sources (DG-RES) at the residential household and commercial customer level in electricity grids

Kamphuis, R. (author), Galsworthy, S. (author), Stifter, M. (author), Esterl, T. (author), Kaser, S. (author), Widergren, S. (author), Galus, M. (author), Targosz, R. (author), Brodén, D. (author), Nordstrom, L. (author), Renting, M. (author), Rijneveld, A. (author), Doolla, S. (author)

Commercial and operational use of residential and commercial user demand-side flexibility in energy grids will play an important but, as yet, not disclosed role in realising the required increase in the penetration of DG-RES. An increased embedding potential is needed to satisfy ambitious energy efficiency and carbon dioxide emission targets....

Transactive control: A framework for operating power systems characterized by high penetration of distributed energy resources

Hu, J. (author), Yang, G. (author), Kok, J.K. (author), Xue, Y. (author), Bindner, H.W. (author)

The increasing number of distributed energy resources connected to power systems raises operational challenges for the network operator, such as introducing grid congestion and voltage deviations in the distribution network level, as well as increasing balancing needs at the whole system level. Control and coordination of a large number of...

Venekamp, G.M. (author), Kamphuis, I.G. (author), Laarakkers, J.A.W. (author), van den Berge, M. (author)

Today, mass presence of distributed energy resources (DERs) connected to the grid is often seen as having adverse effects on grid reliability and robustness. The apprehension is that it complicates or even compromises network management by distribution system operators (DSOs). The central aim of the Open System for Energy Services (OS4ES) [1]...

A Holistic Approach for Low Cost Heliostat Fields

Pfahl, A. (author), Randt, M. (author), Meier, F. (author), Zaschke, M. (author), Geurts, C.P.W. (author), Buselmeier, M. (author)

The AutoR-project takes a holistic approach to reduce the cost of heliostat fields: Wireless control and energy supply enables to use smaller heliostats which need less steel per mirror area (but usually have high wiring cost). A low cost but high efficient drive system is chosen which reduces energy consumption to a minimum amount and leads to...
