摘　　要：针对风电接入后配电系统面临的节能规划、不确定性处理等问题,提出了经济性和社会性兼备的节能改造方案。项目研究风电未接入时,不考虑风电的电力系统节能改造;将点估计法的随机潮流约束应用于风电规划,研究风电并网后的节能策略。研究结果表明,该研究成果不仅可以引导未来风电并网电力系统的节能改造,提高风电的利用效率,而且能获得较好的经济效益,因此具有一定的社会和经济意义。Aiming at the problems of energy-saving planning and uncertainty treatment faced by the distribution system after wind power access,an energy-saving transformation scheme with both economy and society is put forward.When the wind power is not connected,the power system energy-saving transformation of wind power is not considered.The stochastic power flow constraint of point estimation method is applied to wind power planning to study the energy-saving strategy after wind power grid connection.The results show that this research can not only guide the energy-saving transformation of wind power grid connected power system in the future and improve the utilization efficiency of wind power,but also obtain better economic benefits.Therefore,the scheme has certain social and economic significance.
