Intra-day Safe Dispatching Method of New Energy Distribution Network under Load Centralized Control
The operation status of new energy distribution network directly affects the power quality of users.In view of the complex power demands in the role of load centralized control,and the difficulty in judging the consumption capacity and load carrying capacity,the new energy intra-day safe dispatching method is optimized and designed.The new energy distribution network structure model is constructed by integrating the four components of photovoltaic unit,wind power unit,micro gas turbine unit and energy storage unit.It collects real-time operation data and historical operation data of new energy distribution network,predicts and centrally controls the daily load of new energy distribution network.Considering the phenomena of over-load,low voltage,overvoltage and power out of limit at the balance point,the intra-day safe dispatching risk of new energy dis-tribution network is calculated.The dispatching constraints are set from the two aspects of load balance and distribution line ca-pacity to realize the intra-day safe dispatching of new energy distribution network.The test results show that the absorptive ca-pacity and load carrying capacity of this method meet the expected requirements,and the voltage stability coefficient and dis-patching safety risk value are 0.26 and 0.62,which has a good dispatching effect.
