包含多种分布式能源和可控负荷、作为一个可控整体的微网具有灵活的运行方式和可调度性能,既可与主网并网运行,也可以孤岛形式自主运行.在建立各种分布式能源稳态模型的基础上,建立了集中控制模式下的微网优化调度模型,提出了运行和折旧成本最低、环境和综合效益最高等优化目标函数.以一个微网系统为例,讨论了所采用的交互式运行控制策略、优化目标函数以及主网电价类型的不同对系统运行优化结果的影响,验证了所建立的模型的合理性.

Microgrids, which include various distributed energy resources and controllable loads, can be operated and dispatched flexibly. They could operate in both grid-connected and stand-alone modes. Based on steady-state characteristics of distributed energy resources, an optimization and dispatch model for microgrids in the centralized control mode is developed. The objective functions with minimal cost of operation or depreciation, and maximal the environmental or comprehensive benefit are discussed. The optimization and dispatch model is validated by studying a specified case with different interactive operational control strategies, objective functions and power prices.
