Abstract

The invention discloses a projection-based non-iterative coordination method and system for a power distribution network and a power conversion system, and belongs to the technical field of traffic electrification. The method comprises the following steps: firstly, respectively constructing a continuous time battery logistics model of the cross-regional battery replacement system and an economic operation model of each power distribution network; unifying the time scales of the two through an improved discrete time scheme; compressing each power distribution network model into a privacy protection projection space only containing charging power and price signals based on a projection theory; and finally, integrating the space as a constraint into a power conversion system model for one-time solution to obtain an optimal coordination scheme, and issuing the optimal coordination scheme to each power distribution network to complete local scheduling. According to the method, collaborative optimization without iterative data exchange among multiple systems is realized, and the global operation economy and the calculation efficiency are remarkably improved while the sensitive data of each operator is hidden.
