It is reported that as of December 31, 2018, 60 user-side energy storage power stations have been built in Jiangsu province, with a total energy storage capacity of 97MW and 691MWh, among which 48 energy storage projects have a total capacity of 93.7MW applied to peak cutting and valley filling. The application scenarios of user-side
Thus, a three-layer optimization model of "pricing on the power supply side–basic scenario configuration on the user side–worst-case scenario scheduling on the user side" is formulated. Through relaxing the state variables of energy storage in the configuration and scheduling models and combining Karush-Kuhn-Tucher conditions, the
Under a two-part tariff, the user-side installation of photovoltaic and energy storage systems can simultaneously lower the electricity charge and demand charge. How to plan the energy storage capacity and location against the backdrop of a fully installed photovoltaic system is a critical element in determining the economic
