Through implementing different prices during different time periods, TOU price can stimulate the electricity consumption changes and promote more flexible supply-demand interaction . Furthermore, the TOU price can also reduce energy costs and enhance the stability of the power system.
Using dynamic time-of-use electricity prices can more flexibly obtain the capacity configuration scale of energy storage. The article adopts the capacity and maximum power values of energy storage configuration in each season, which can meet the demand for energy storage capacity in each season.
This further demonstrates that the optimized time-of-use electricity price is conducive to further improving the on-site consumption rate of new energy. Figure 5. Configuration of energy storage before and after demand response. Table 4. Optimization results of typical days in three Seasons.
Scenario 4 has the highest on-site consumption rate of new energy, as the optimized time-of-use electricity price through the outer layer provides the inner layer with a load that has undergone demand-side response.
The results of the case study indicate that the optimal TOU price obtained from the proposed model can not only instruct users to discharge the electricity storage orderly and guarantee the stability of distributed energy resources to grid, but also reduce the waste in total cost of power supply chain.
According to the characteristics of electricity consumption, loads can be divided into two categories: fixed load and flexible load. In grid-connected wind and solar energy storage systems, wind and solar power are prioritized for supplying local loads, and excess electricity can be sent to the external power grid.
