摘要(Abstract):
随着新能源的发展,更多具有随机性的分布式电源以微电网群的形式接入配电网,传统集中式经济调度将面临复杂信息交互的挑战。此外,微电网群灵活多变的拓扑结构也迫切需要考虑数据隐私的微电网群信息交互机制。针对微电网群分散自治的特点,提出一种考虑微电网群信息交互的微电网群新能源互补消纳与协同优化调控算法,以降低功率调节所耗费成本和保证微电网整体实时功率平衡为目标,将经济调度问题转换为功率分配过程中微增成本一致性的问题。算例仿真结果表明,所提分布式算法具有良好的收敛性,且在功率约束、拓扑变化、链路故障的情境下仍具有较好的优化效果。
With the development of renewable energy sources(RESs), more distributed generators with random nature are connected to the distribution network in the form of microgrid clusters. Meanwhile, the traditional centralized economic dispatch also faces the challenge of complex information interaction. In addition, the flexible topology of microgrid clusters urgently requires a information interaction mechanism considering data privacy for microgrid clusters. To address the decentralized and autonomous characteristics of microgrid clusters, an optimal dispatch algorithm of complementary consumption and collaboration for RESs considering information interaction in microgrid clusters is proposed. The proposed algorithm takes reducing the cost of power regulation and guarantying the overall real-time power balance of the microgrids as the goal, and transforms the economic dispatch problem into the consensus based problem of incremental cost in the power distribution process. Case simulation results show that the proposed distributed algorithm has good convergence and obtains good optimal effect under the conditions of power constraints, topology changes and link failures.
