Abstract: This paper takes photovoltaic poverty alleviation as the research background and takes into account farmers' demands for photovoltaic (PV) income, and proposes an optimization configuration of distributed generation considering photovoltaic grid-connected income. The model is built with the goal of minimum network loss, minimum total investment and operation cost and maximization of photovoltaic grid-connected income, simulated annealing particle swarm optimization is used to solve the model, the feasibility and effectiveness of the model is proved by an example of IEEE 33 nodes system, this paper provides the technical support and theory reference for the construction of photovoltaic (PV) poverty alleviation projects in poverty-stricken areas in China.
