Energy Storage Systems: Coordinated and Optimised Control for an Economic Integration to the Power Grid

The balance of energy demand and supply leads to essential developments in Energy Storages (ES) to be efficient, flexible and reliable in the electrical grid system. This role will allow immediate responses to possible power fluctuations within the network and storage of excess generation in order to sustain a stable system and provide energy following a catastrophic failure in the electric grid.
A main issue with Renewable Energy Sources (RES) is the unpredictability of its power generation causing negative impacts on the grid. RES variability is currently controlled based on the irregular ramping of conventional reserves relative to the load and weather forecast. However, with increased levels of RES penetration, the less the conventional reserve compensation becomes adequate.
This research demonstrates the potential benefits of optimised positioning and coordination control of ES systems in managing the rising deployment of intermittent generation, thus allowing the grid to be more resourceful in providing electricity to the required locations by the required times.
Formed strategies will be thoroughly investigated, examined and evaluated on various UK distribution network models. The purposefully chosen network models consist of diverse levels of RES penetration with the intention of inspecting the economic benefits and validating the effectiveness of the control strategies with the aid of the ES ancillary service to position, optimise and enhance the stability and consistency of the grid.
