A control strategy of battery energy storage system and allocation in distribution systems

This paper proposes a practical model and efficient method for the distribution companies. The optimal allocation and control of the BESS can help the DISCO mitigate the risk of the energy trading regulated market. Especially the distribution system with high penetration of renewable energy, the BESS can reduce the loss caused by the uncertainty of the demand and distribution generators. The effectiveness of the proposed project has been tested with comprehensive case studies. From the case study results, the distribution company can save money through optimal planning and lay down a more suitable energy purchasing plan. Meanwhile, the BESS optima allocation method is proved to be effective. Along with the battery technology development and more stimulus policies introduced, the costs of battery will decrease, which makes the BESS more feasible.
