The Internal Resource Aggregation Strategy of Virtual Power Plants Based on Different Basic Configurations

摘要

An internal resource aggregation strategy of VPP based on different basic configurations is proposed according to VPP`s preferences for different DERs. Characteristics of DERs are described at the beginning. Then an aggregation model of internal resources, which takes into account the operational characteristics of DERs and constraints of power system, is established aiming at maximizing the VPP`s profit in the day-ahead market. Multi-scenario method is used to deal with uncertainty of DERs. The combination form of VPP`s internal resources and output of each DER in different scenarios are derived from the model. The results of case study show that the combination form of DERs varies with the change of operation scenarios. There is a significant demand for the flexible DERs in every kind of scenario. Meanwhile, comparing with others, VPP which is with flexible DER as basic configuration can obtain a larger profit.
