Optimization of Power Flow Scheduling in Distribution Networks with Distributed Power Considering Demand Response and Network Structure Optimization
The grid connection of distributed power sources such as wind power and photovoltaic brings huge challenges to the safe and economic operation of distribution network trends.In order to improve the safety and economy of distribution network operation,a distri-bution network trend scheduling optimization model considering demand response and network structure optimization is proposed.First-ly,demand response is introduced into the distribution network scheduling model to adjust the electricity load of the distribution net-work,making the electricity load more adaptable to the output situation of distributed power sources.Subsequently,using the"non ho-mology"phenomenon as a theoretical basis to optimize the power grid structure can release the power transmission capacity of the grid.Then,an energy storage system is introduced into the system distribution network model to alleviate the fluctuation of distributed power sources.The economic efficiency of distribution network power flow operation is improved through the synergistic effect of source net-work load storage from multiple perspectives.IEEE24 nodes are taken as an example for simulation analysis,and the Cplex solver is called using MATLAB software to solve the constructed model.The simulation results show that the model proposed can effectively im-prove the economy of distribution network power flow and reduce the operating cost of the system.
