为了提高微电网建设运维的经济性,满足多种不同类型微电网对可靠性的个性化需求,提出一种适应多场景的微电网一体化柔性规划方法.以类型与组成判断结果为依据,建立包含容量规划与网架规划的双层模型.下层容量规划以微源建设运行成本最小为目标,采用混合整数优化算法求解;上层网架规划以网络建设运行成本最小为目标,采用粒子群算法求解,形成了组成判断-容量规划-网架规划的闭环一体化规划系统.系统可通过灵活调整独立运行持续时间约束以及对负荷停电重视程度参数,满足不同微电网对可靠性的个性化需求.算例表明:所提方法可有效降低微电网的建设运维成本,对多种类型与组成、多种可靠性需求的场景均具有良好的适应性.

In order to improve the economy of microgrid construction and operation, and meet the personalized demand for reliability of various types of microgrids, an integrated flexible planning method for microgrid is proposed to adapt to multiple scenarios. Based on the judgment results of type and composition, a two-layer model including capacity planning and grid planning is established. The lower-level capacity planning takes the minimum operation cost of micro-source construction as the goal and adopts the mixed integer optimization algorithm to solve it. The upper layer grid planning takes the minimum cost of network construction and operation as the goal, and uses the particle swarm optimization algorithm to solve it. A closed-loop integrated planning system consisting of judgment, capacity planning, and grid planning is formed. The system can meet the personalized reliability requirements of different microgrids by flexibly adjusting the independent operation duration constraints and the load outage attention parameters. The example shows that the proposed method can effectively reduce the construction and operation cost of microgrid, and has a good adaptability to different types and components and different reliability requirements.
