Research on user energy storage optimization system considering a grid-on new energy

摘要

As the proportion of new energy in the power grid continues to increase, it brings many challenges to the optimal dispatch of traditional distribution networks. The optimal dispatch strategy of the active distribution network is a key technology that needs to be improved, and the optimization of user energy storage is of great significance. The optimal dispatch strategy of the active distribution network includes many aspects such as source, load, and storage. This paper only considers the optimal charging and discharging strategy of the user's energy storage equipment after the new energy is connected and builds the user's energy storage system cost model, user revenue model, new energy electric field revenue model after energy storage equipment is connected, and energy storage equipment charging and discharging model. The results show that the energy storage optimization proposed in this paper can ensure the interests of the power supply side, the user side, and the power sales company, and is more conducive to mobilizing the three parties to participate in the user load response and energy storage equipment access under time-of-use electricity prices.
