Analysis and Research on Dispatch of Power Economy Based on New Energy Source

With the increasing global demand for new energy sources,new energy sources such as wind and solar energy have gained widespread attention and gradually become an important part of the energy system,but due to their random and intermittent characteristics,they also have an impact on the stable operation of the power system.This paper introduces new energy sources into the economic dispatch of power system,builds a power system economy dispatch model based on the combination of multiple energy sources,and introduces new energy capacity into the cost control function of power system economic dispatch.Simulations of the dispatching model are conducted,and the results show that the cost of power generation decreases significantly after the new energy generation is connected to the grid,proving the economic benefits of new energy.Under the condition of conducting economic dispatch based on new energy combination,the output power of multiple energy sources combined with grid-connected power generation is more stable,which strengthens the balance of supply and demand of the power system.This power economy dispatching scheme is suitable for large-scale application under the condition of joining new energy sources to the grid.
