Optimal Configuration of User-Side Energy Storage for Multi-Transformer Integrated Industrial Park Microgrid

Under a two-part tariff, the user-side installation of photovoltaic and energy storage systems can simultaneously lower electricity charge demand charge. How to plan capacity location against backdrop fully installed system is critical element in determining economic benefits users. In view this, we propose an optimal configuration for multi-transformer-integrated industrial park microgrid. First, objective function planning built with income cost whole life cycle as core elements. This conducted by taking into consideration time-of-use price, on-grid operation maintenance costs. Then, considering load characteristics bidirectional interaction different nodes, decentralized model developed Finally, combined engineering practice constraints, solved mixed integer linear programming. The simulation test demonstrates how proposed successfully increase park. Electricity costs are reduced 11.90% 19.35%, respectively, accommodation level increased 4.2%, compared those without system.
