摘要:

针对海岛微电网分布式电源和负荷的独有特性,以海岛系统运行经济性为目标,考虑新能源消纳因素,提出一种海岛微电网能量优化调度方法。首先在分析典型海洋能发电出力特性的基础上,建立了含风、光、柴、储、波浪能、潮汐能以及可控负荷的海岛微网能量优化调度模型;而后面向日前和日内2个时间尺度,采用CPLEX完成混合整数规划,利用日前调度计划与日内实时滚动推演结果比对,依据日内滚动计算结果修正日前调度计划,实现当日微网能量调度全局最优。算例分析表明,由于利用了日前和日内相结合的滚动计算方法,使对岛上源、荷的预测精度逐级提高,该优化调度方法在兼顾海岛微电网功率平衡和可再生能源利用率的同时,最大限度降低了海岛微电网运维成本。

Abstract:

In view of the exclusive characteristics of distributed sources and loads in the island microgrid, an optimal energy dispatching method for island microgrid is proposed in this paper to achieve economic operation while considering renewable power accommodation. Firstly, according to performance analysis of typical ocean power generation, the optimization model of energy dispatching for island microgrid is constructed involving wind power, photovoltaic power, diesel engine generating sets, energy storage devices, wave power, tidal power, and controllable loads. Then, on the two timescales of day-ahead and intra-day, microgrid power dispatch for the day could achieve the global optimum by using mixed integer programming on CPLEX, in which the day-ahead schedule is revised continuously in accordance with the intra-day scrollable calculation results by comparing with the intra-day real-time scrollable deductive results. The analysis shows that, by taking advantage of day-ahead and intra-day combined scrollable calculation, the prediction accuracy of the sources and loads on the island can be improved step by step, and the proposed dispatch optimization method can achieve power balance and higher renewable energy utilization while minimize the operation and maintenance costs of island microgrid.
