Research on Photovoltaic Power Capacity Optimization in Microgrid

An optimization model to get the optimal capacity of photovoltaic connected to the microgrid aimed at reducing the loss and satisfying the node voltage constraints is proposed. A microgrid with n nodes and n-1 feeders is taken as an example to set a linear programming model. Taking a microgrid with 11 nodes, first sensitivity analysis method is applied to determine the best location of the photovoltaic power, and then the optimal value of the PV power capacity is calculated by the Matlab programming. Finally, the curve of the relationship between loss and the capacity of the ptotovoltaic power is plotted through Matlab, which qualitatively verifies the feasibility and practicality of the method.
