Most of the renewable energy sources have unstable supply and high volatility. With growing share in integrated system, it is more difficult to execute pre-dispatch regulation decision system. To address problem increased volatility study proposes optimize decision-making system’s control center by analyzing difference between day-ahead market clearing price declared electricity supply. The results show that node power much higher than ground's actual during period from 1:00 am 4:00 am. During this nodes at 2500kW around 1500kW. outgoing system electrical load can be reduced advance 10 3 pm. proposed on basis ensure stability operation while reducing operating cost
