微电网规划关键问题与运行仿真
摘要：微电网的合理规划是实现其效益的基础。本文从负荷预测、接入方式、电压等级和容量以及网架结构4个方面对微电网规划的关键问题进行研究。利用电磁暂态仿真软件EMTDC/PSCAD建立了含微型燃气轮机、风力发电机、光伏电池等分布式电源的微电网模型及其控制模型,对微电网运行模式切换后功率变化、频率稳定性、电压稳定性等运行情况进行仿真。实验表明,上述规划方法对工程实践具有一定的指导作用。
Abstract:Reasonable microgrid planning is the basic for the obtaining of benefit. Such key issues on microgrid planning as the load forecasting, access mode, voltage level and capacity, and grid structure are studied in this paper. By using the electromagnetic transient simulation software EMTDC/PSCAD, microgrid model with distributed generations that include microturbines, wind turbines and photovoltaic cells and its control model are built, and such cases as the power variation, frequency stability and voltage stability after switching operation modes are simulated. Experiments show that the proposed method has certain reference for engineering application.
