BESS LOCATED IN PRIMARY SUBSTATION FOR RES INTEGRATION AND ANCILLARY SERVICES PROVISION

In this paper a model for simulating provision of multiple services via Battery Energy Storage System (BESS) is presented. The results of several sets of simulations are proposed. Applications analysed are renewable energy source support and provision of frequency regulation via BESS. The approach proposed is designed with respect to many directions: the system operator perspective (accuracy and reliability of the service provision are the main goals); the economic viability perspective (highlighting capex, cash flows, return on investment); the technology perspective (i.e. evaluating the impact that different setpoints could have on the BESS state of health), via qualitative and quantitative analysis of the level of exploitation of the system. The final goal is to evaluate the feasibility in the provision of multiple services simultaneously.
