Sizing and Optimal Control of Energy Storage in Energy Markets

Dear Colleagues,

We are very pleased to introduce this Special Issue of the journal Sustainability on “Sizing and Optimal Control of Energy Storage in Energy Markets”.

Renewable energy sources (RES) are today a rising solution to face climate change, environmental pollution and increasing global demand on energy. Renewable energies cover over 20 % of electricity generation, and more than 10% of the total final energy consumption worldwide. Over the last few years especially, variable renewable energy sources (VRES) are experiencing worldwide development.

Nevertheless, the integration of VRES in grids also involves some challenges related to stability and reliability which are mostly caused by the high uncertainty of their production forecast and variable nature. The stochastic nature of the VRES affects the production of energy, unbalancing the system. This reduces their controllability, complicates the operation of the system, notably from the economic point of view compared to other more traditional electricity generators. This calls for increased flexibility of the energy networks.

Dedicated and non-dedicated storage facilities are considered as one of the most promising solutions to tackle the fluctuating nature of VRES while helping the grid to be more resilient to variations. Storage facilities in this context can range from conventional pump storage facilities over battery energy storage systems to aggregated electric vehicles with V2G capability as well as more diverse options like Power-to-X, CAES, flywheel, thermal storage (cogeneration), etc. In that context, sizing and optimal control of energy storage is a key topic for further integration in energy markets, targeting the increased development of flexibility offers. This is the motivation of the present special issue.

We are targeting researchers developing methods to ensure the (possibly co-)optimal sizing and control and likely the location of storage facilities for addressing different energy markets while generating solutions for technical constraints (congestions, exchanges between distribution and transmission and so on). The definition of new energy markets (like markets dedicated to local energy communities, or peer-to-peer energy trading) can be part of this Special Issue. In that context, solutions aiming at the fulfilment of grid codes by optimizing the production, aiming at controllable power sources to reduce intrinsic variability, developing innovative controls for energy markets integration, proposing hybrid storage systems for multiple time horizon energy markets or simply improving the economic viability of energy systems via sophisticated energy management and business model, are welcome.

To summarize, this Special Issue is looking for contributions on the following topics: cutting-edge sizing and control algorithm for energy storage, multi-tasking and participation in various markets (from aFRR to more traditional capacity markets) and innovative hybridization of technical solutions or system-oriented modelling for optimization.

MDPI and the editors of Sustainability are delighted to have the privilege of publishing this Special Issue. We wish to thank all the authors that will consider contributing to this Special Issue
