Distribution network energy loss calculation method considering wind power integration

Grid energy loss is one of the key factors affecting the economic operation of power systems. Accurate calculation of electric energy consumption, will have a great positive effect on the planning, operation and management of all aspects of the grid. Due to the randomness of wind power resources, wind power is likely to increase access or may reduce power system losses. Therefore, study on grid energy loss calculation method containing wind integration has very important practical significance. Currently there are many grid theoretical line loss calculation method, but these methods have some limitation such as, less considering the load curve changes. This paper presents an improved method of equivalent power to calculate energy loss of wind power integration, through considering the impact of the load curve, and the random fluctuations of wind power, making use of load shape coefficient to correct the average power, computing power flow calculation by using equivalent power, calculate the energy loss more accurately.
