Conclusions This article studies the allocation of energy storage capacity considering electricity prices and on-site consumption of new energy in wind and solar energy storage systems. A nested two-layer optimization model is constructed, and the following conclusions are drawn:
The market environment is an important factor affecting the bidding on grid of new energy, which needs to be considered in the formation mechanism of on grid price of new energy. For the above analysis, the research done in this paper is compared with the existing research, as shown in Table 1.
If is within the power supply capacity of the interconnection line, the external power grid should consider charging the energy storage system while supplying electricity; When is less than zero or greater than zero and less than , this situation mainly relies on the energy storage system to maintain the balance of .
This article proposes a coordinated optimization method for energy storage and electricity prices in the park, which can achieve maximum on-site consumption of new energy while improving the economy of energy storage to a certain extent.
Author to whom correspondence should be addressed. Configuring energy storage devices can effectively improve the on-site consumption rate of new energy such as wind power and photovoltaic, and alleviate the planning and construction pressure of external power grids on grid-connected operation of new energy.
