The annual electric power consumption is one of the most important factors in operation decisions of Chinese electric power generation groups. The grey model is feasible method to deal with this trend extension problem with few data. But the simple approximation in dispersing the first order differential equation affects it forecasting precise. Based on adjusting the positions of each particle, the...
With the deterioration of primary energy market supply, it is important to optimize the raw material buying and dispatching. The annual electric power consumption is one of the most important decision making basis to realize this. Because of the characters of observations, OLS method and neural network model are all not suit for this. PLS extract variables one by one from few historical data. Under...
After China electric power industry market reform, electric power generation groups has competed for exploiting electric generation natural resources. With the consumption of good investment projects, generation groups will put more and more importance on investment risk. This paper adopts Lagrange multiplier to solve the problem of portfolio quadratic programming and further brings forward power...
