Stochastic operation optimization of grid-connected photovoltaic microgrid considering demand side response

In the face of the upcoming pressure of energy crisis and environmental problems, the use of solar photovoltaic (PV) power generation has become one of the focuses of the human being. An optimal operation method for photovoltaic microgrid under uncertainty is studied based on the demand side response mechanism in this paper. Monte Carlo simulation is used to simulate the uncertainty of PV and load. The demand side response mechanism is introduced to control the peak load and valley load transfer. Then a chance constrained programming based optimal operation model of PV microgrid is built. The model takes maximum absorption of PV power generation as the objective. The particle swarm optimization algorithm is used to solve this optimization problem. The simulation results prove the validity of the proposed method.
