With the rapid development of new energy generation technology,photovoltaic power generation system is being accessed to the distribution network on a large scale,but the distribution network voltage control is a difficult problem.Based on the reactive power regulation of photovoltaic power generation system,this paper proposes a new type of distribution network voltage control strategy,which sets the voltage alarm interval,carries out the voltage control when the voltage reaches the alarm interval and there is a tendency to go beyond the alarm limit,so as to ensure that the voltage is controlled in a reasonable interval,and determines the regulating order and regulating method through the voltage regulating factor and voltage cost factor.In the simulation environment to build a simulation model,the control strategy proposed in this paper and other control strategies for comparative study,the control strategy proposed in this paper can be more effective to improve the voltage quality,and to achieve the scientific control of the cost of regulating the voltage,has a certain degree of superiority,and can be large-scale popularization and application.
