基于一致性理论的独立微电网分布式动态经济调度
Consensus-based Distributed Dynamic Economic Dispatching for Islanded Microgrids
摘要
Abstract
The islanded microgrid is an effective approach for improving the utilization rate of renewable resources, and the dynamic economic dispatch is a vital part of microgrid operation. This paper provides a model of dynamic economic dispatch for islanded microgrids, and proposes a consensus-based distributed method of implementation. The system optimization is realized through the local computation and a little neighborhood information exchange among the units. The approach is comprised of two stages. In the first stage, each unit obtains systemic information by the average consensus algorithm, then the power demand scheduling for the controllable loads can be pre-arranged to maximize the utilization of renewable energy. In the second stage, the dynamic optimization problem is decomposed into a series of single-period economic dispatch problem by updating the upper and lower output boundaries of generators or energy storage systems in each time period. Then a pinning consensus algorithm is used by each unit to calculate the optimal output of each time period based on the equal incremental rate criteria. Simulation results are presented to demonstrate the validity of the proposed model and approach.关键词
