Abstract

The invention relates to a distributed photovoltaic power generation control method for adaptively adjusting reactive power output. The distribution network system in the area is connected to photovoltaics, and the photovoltaics participate in the absorption or emission of reactive power. According to the sunshine intensity, temperature and local load data of the area, the output power value of photovoltaics is calculated, and the output power of photovoltaics is obtained. The upper limit value of work power; then, the reactive power control in the distribution network system is optimized by using the particle swarm optimization algorithm by setting the initial value and the objective function. The invention utilizes the particle swarm algorithm to optimize the reactive power output by photovoltaics, which effectively improves the problem of poor power quality.

Description

technical field

[0001] The invention relates to a distributed photovoltaic power generation control method for adaptively adjusting reactive power output, and relates to the field of reactive power optimization and control of power systems. Background technique

[0002] Solar photovoltaic power generation, as a clean and efficient way of generating electricity, has been widely concerned and favored by people in recent years. However, due to the strong randomness and discontinuity of photovoltaic power generation, when a large number of photovoltaics are connected to the power distribution system, the complexity of the operation control of the power distribution system will increase significantly, and sometimes it will even cause the load distribution of the entire distribution network to change dramatically. Large changes, which will have an impact on the loss of distribution lines and the voltage of the distribution network, as well as the operational safety and economy of ...
