The optimal configuration of energy storage capacity is an important issue for large scale solar systems. a strategy for optimal allocation of energy storage is proposed in this paper. First various scenarios and their value of energy storage in PV applications are discussed. Then a double-layer decision architecture is proposed in this article.
The investment cost of energy storage system is taken as the inner objective function, the charge and discharge strategy of the energy storage system and augmentation are the optimal variables. Finally, the effectiveness and feasibility of the proposed model and method are verified through case simulations.
Furthermore, Battery Energy Storage Systems (BESS) devices are treated as negative or positive PQ loads: BESS charging power (positive values) is considered as load, while discharging power (negative values) is regarded as generation. All decision variables are intrinsically linked to the objective functions.
Without DG and BESS integration, total losses at this load point were 202.7 kW, with the cost of active power integration from the upstream grid station at $172,671.8 per hour and an emission rate of 8022.2 t/h. The upstream grid station adjusted the overall load demand and losses by integrating 3.9177 MW of power.
Systems for storing energy in batteries, or BESS, answer these issues. Battery energy storage systems (BESS) are essential in managing and optimizing renewable energy utilization and guarantee a steady and reliable power supply by accruing surplus energy throughout high generation and discharging it during demand.
Initially, base-case load flow calculations were performed for the test systems without Distributed Generation (DG) sources. The active power losses over 24 h were found to be 3.0021 MW per day. The base voltage and MVA of the proposed test network are 12.66 kV and 10 MVA, respectively.
