摘要
静态安全分析是电力系统能量管理系统重要的高级应用软件模块。由于测量、传输等过程中误差,以及风电、太阳能发电等新能源的大量接入,致使电力系统运行状态存在随机性和不确定性。不计及随机因素的电力系统静态安全分析问题已难以满足应用需求。分析了风电场风速的随机特性,研究了风电场随机输出功率,提出了电力系统静态安全概率分析问题。采用鲁棒性优越的蒙特卡洛方法求解概率潮流,IEEE-118系统的测试结果验证,模型与方法的有效性和可行性。
Static security analysis is an important high-level application software modules of energy management system （EMS） for power system. The data measurement and transmission error, as well as a large number of new energy sources like as wind power, solar power, lead to the presence of randomness and uncertainty of the power system operational sta- tus. Power system static security analysis without account random factors has been difficult to meet the application re- quirements. This paper analyzes the random nature of the wind speed of the wind farm, researches the random output power of the wind farm, and proposes the problem of probabilistic static security analysis for power system. Excellent ro- bustness Monte Carlo method is applied on solving the probabilitic power flow, the effectiveness and feasibility of the pro- posed model and method is verified through the IEEE-118 system test results.
