Multiple Virtual Power Plants Transaction Matching Strategy Based on Alliance Blockchain

Virtual power plants can aggregate distributed energy resources and interruptible loads in a region for coordinated regulation unified transaction. However, with the diversification of competition electricity market, operation mechanism between multiple virtual (multi-VPPs) has gradually become research focus. Based on this, this paper proposes new type transactions strategy multi-VPPs, i.e., transaction matching mechanism. A two-stage model based is constructed multi-VPPs to participate day-ahead intraday trading markets. In first stage, each VPP optimizes its own internal units’ output external interaction through cooperative game; second it among that match most suitable counterpart by flexible price setting increase benefits all VPPs. Considering efficiency security blockchain technology, we choose complete support alliance technology improve speed system solution.
