abstract

• This paper introduces a novel approach for the optimal placement of battery energy storage systems (BESS) in power networks with high penetration of photovoltaic (PV) plants. Initially, a fit-forpurpose steady-state, power flow BESS model with energy time shift strategy is formulated following fundamental operation principles. The optimal BESS placement methodology is subsequently developed in the realm of incremental modelling of power system losses, which permits to identify the best candidate node for the BESS connection that reduces the total power losses. And for practical results, daily varying patterns of nodal demand, generation dispatch and solar irradiance are considered, all this accompanied by the BESS operating strategy, i.e., electric energy time shift, which is one of the most sounding strategic applications in current BESS facilities. In addition to providing a suitable validation proof using the standard IEEE 5-bus test system, two practical test power network models with 24 and 118 nodes are used to showcase the usefulness of the incremental modelling approach for optimal BESS placement in power grids with high penetration of PV plants. & COPY; 2023 Elsevier Ltd.
