基于逆变器与SVG协同运行的优化策略研究OA

Aiming at the problems of power factor fluctuation and high plant electricity consumption rate in on-grid PV power generation systems,this paper proposes a time-of-day dynamic collaborative control strategy.By optimizing the operating modes of inverters and Static Var Generators(SVG),the system performance is improved.The research results show that the collaborative strategy effectively stabilizes the system power factor within the range of 0.92～0.95,successfully avoiding the risk of grid assessment.Meanwhile,it reduces the plant electricity consumption rate from 5%to 2.5%,saving an average of about 720000 yuan in electricity costs per year.In addition,the average daily operating time of the SVG is shortened by 10 h,and the equipment life is extended by 20%to 30%.In terms of economic benefits,the collaborative strategy reduces the initial investment by 15%to 20%by decreasing the redundancy configuration demand of SVG capacity,and can reduce economic losses by about 3.2 million yuan per year throughout the life cycle.In terms of technological innovation,the collaborative strategy introduces a threshold algorithm,which significantly improves the system's response speed and adaptability,providing a solid theoretical and practical support for the efficient operation of new PV stations.
