Study on the Coupling System of Building Flexible Energy and Energy Storage on Power Grid Operation Performance

The flexible building energy storage coupling dispatching framework and optimal dispatching model have been established in this paper by using the multi-levels network dispatching analysis method of the grid system. It would include solving the optimization model with the objective function having the minimum standard deviation and the constraint conditions of charging and discharging power and capacity. Second, a simulation analysis who used an example is implemented based on the typical daily load of a Tianjin district. The findings indicate that: energy storage, construction, and flexible energy use The joint optimization’s respective standard deviations are 1.40, 1.59, and 1.24. The system’s power storage, peak-clipping, valley-filling, and other features have a greater impact than the flexible energy use of a standard structure. The building’s flexible energy use has a good peak shaving effect, which can compensate for the problems caused by the general battery energy storage system’s power and capacity limitations during the generation capacity period. In addition, the battery energy storage system can use the valley time to charge, resolving issues with valley filling optimization and the lack of flexible energy use in buildings. From this, it can be seen that the power storage system and the building’s flexible energy use jointly regulate the overall energy use performance of the structure, which not only achieves good peak load cutting and valley filling effect but also controls other issues such as frequent load fluctuations, large load peak valley difference, and other issues, ultimately leading to high energy utilization in China.
