Abstract: |
Formulating reasonable coordination operation strategy of wind-photovoltaic-battery generation system can improve the operation economy of the new energy electric power enterprises. A hybrid algorithm of variable weight coefficient and associated rules mining is proposed in order to optimize coordination operation strategy of wind-photovoltaic-battery generation system. First, it mines the optimal combination under all conditions as well as comprehensive performance index of a unit based on historical operating data, and forms a set of inference rules between condition and the optimal combination. Second, according to the specific scheduling requirements and working environment, it uses the equilibrium function of variable weight comprehensive mode, and calculates the variable weight coefficient of potential target model. Combining with the fixed performance evaluation method, it selects the optimal configuration mode, builds a set of objective, real-time, accurate coordinate operation strategy, and optimizes the system operation cost. Finally, the simulation proves that the algorithm can make full use of complementary of wind and solar resources, extend the service life of the battery, and improve economic efficiency of system. |
