The development of energy storage systems allows us to consider their usage for load profile leveling during operational planning on electricity markets. The paper proposes and analyses an application of an energy storage model to the electricity market in Russia with the focus on the day ahead market. We consider bidding, energy storage constraints for an optimal power flow problem, and locational marginal pricing. We show that the largest effect for the market and for the energy storage system would be gained by integration of the energy storage model into the market’s optimization models. The proposed theory has been tested on the optimal power flow model of the day ahead market in Russia of 10000-node Unified Energy System. It is shown that energy storage systems are in demand with a wide range of efficiencies and cycle costs.

This paper deals with an efficient method to ensure an optimal power flow in water pumping system based on renewable energy. In this context, this study aims to find a global supervisory strategy with an optimal adjustment of the DC-bus voltage enhancement. In the proposed study, a firefly algorithm is employed as the key optimizer of the supervisory power exchange in order to improve the different power flows exchanged among the system devices. The water pumping system (WPS) is made up of a wind turbine (WT) required as the principal renewable energy source associated to a battery energy storage system (BSS) to ensure the power supply continuity of a moto-pump system. The models of WPS units and the control strategy are developed using MATLAB software. The simulation results are provided to show the considerable improvement for the system as regards both of voltage stability and the feasibility of power management strategy.
