The core function goal of virtual power plant (VPP) is to integrate all kinds of flexible resources driven by value, participate in all kinds of transactions in power wholesale market, provide capacity and auxiliary services for power grid operation, improve the economy and reliability of power system, and promote the efficient optimization and integration of renewable energy. However, there is no effective research on the income distribution mechanism of virtual power plant. This paper constructs a set of index system to measure the valuable contribution of each aggregated resource, and distributes the income reasonably according to the final valuable contribution of each aggregated resource. The actual example shows that this income distribution mechanism can effectively balance the interests of all parties and achieve a win-win situation of the system.

This paper mainly studies the capacity allocation of off-grid electric vehicle charging stations. On this basis, a capacity allocation optimization model of "wind-light-storage-charging" multi-station fusion system is proposed. The model aims to minimize the cost of investment, construction, operation and maintenance of charging stations, and takes into account the local wind and light resource endowment, charging load demand, reserve capacity and other random factors and constraints. In this paper, the model is implemented based on GAMS software, and a typical case is analyzed to verify the correctness and effectiveness of the method.
