Co-configuration method for PV prosumers based on multiple uncertainties and interactive operation

The distributed photovoltaic (PV) and energy storage system has transformed power users into PV prosumers. To consider the impact of the upper grid tariff and PV output uncertainty on the configuration, and to reflect the interactive relationship between the PV prosumers and Distribution Network Operators (DNO), a collaborative configuration method based on multiple uncertainties and interactive operation is proposed. First, the planning and operating framework of the interaction between PV prosumers and DNO is constructed, and the operational interaction characteristics of PV prosumers and DNO are embedded into the planning problem. Second, in order to cope with the uncertainty of PV output and tariff between DNO and the upper grid, dual theory and robust optimization methods are introduced to convert the maxmin problem in DNO into a max problem and the minmax problem in the PV prosumers into a min problem, and the Karush-Kuhn-Tucker(KKT) condition is used to equate the PV prosumers model to the equilibrium condition in DNO model, the two-layer interactive model is equivalent to a single-layer problem and solved by using YALMIP/CPLEX solver. Finally, the effectiveness of the proposed method for joint planning of photovoltaic and storage system are demonstrated by examples.
