Synergistic Optimization Strategy Considering the Integration of Electric Vehicles and Renewable Energy into the Grid

With the increase of power equipment in the society year by year, it brings great potential danger to the safe and stable operation of the distribution network. In order to reduce the network loss of the distribution network and ensure its safer and more stable operation, this paper achieves the target demand by coordinating the operation and scheduling of various renewable energy sources and electric vehicles. Firstly, the models of various new energy sources and electric vehicles are parameterised and their operating conditions are constrained to achieve the prediction of input and output power. Second, the network loss objective function is established and three Options for the actual operating conditions are set. Then, the improved IEEE-33 node is established for simulation verification, and the feasibility of incorporating renewable energy sources and electric vehicles as well as adopting second-order cone optimisation is verified by the power comparison graphs, the network loss graphs and the voltage specification comparison graphs of multiple Options. The objectives of reducing network losses and lowering grid voltage stress are effectively achieved.
