Research on Array Spacing Planning in Photovoltaic Integrated Distribution Network
As the number of photovoltaic power plants gradually increases,the problem of inter-array shading is particularly serious.Unqualified photovoltaic power plant planning results is a substantial reduction in power generation.To maximize the power generation of photovoltaic power plants,an array spacing planning research in photovoltaic integrated distribution network is proposed.Bifacial battery are used to improve the structure of solar fixed racking,and the power generation of solar fixed racking is calculated.Based on obtaining the optimal rotation frequency,the photovoltaic array is divided into two spacing setting modes,step and slope,with the constraints of power generation and optimal rotation frequency setting.Through the array spacing planning,the objective function of maximizing power generation and minimizing rotation frequency is taken as the arrangement principle to complete the array spacing planning design for photovoltaic integrated distribution network.The experimental results show that the planned photovoltaic power plants has an energy storage capacity higher than 4 000 kWh;the repetition rate of array spacing planning is lower than 4.8%;the optimal rotation frequency turns out to be 5 times/d.The research can improve the power generation of photovoltaic power plants and ensure the rationality of the overall structure of photovoltaic power plants after accessing the distribution network,which has strong engineering application value.
