Due to the volatility, randomness and seasonality of the load, there is no effective prediction model for the load development trend after the large-scale "coal to electricity" access to the rural distribution network, which affects the capacity planning of the rural distribution network. Aiming at this problem, this paper deeply analyzes the load characteristics and influencing factors of "coal to electricity" in rural areas, puts forward a screening method of single forecasting model based on grey correlation degree and effectiveness index, establishes the optimal medium and long-term combined forecasting model of "coal to electricity" load, and puts forward the flow chart of forecasting model. Finally, an example based on the historical data of a typical "coal to electricity" area is given to verify the results. The results show that the combined forecasting model can further improve the accuracy of the medium and long-term load forecasting results of "coal to electricity" through dynamic weighted optimization of the combined forecasting results.
This paper proposes an integrated energy service method for thermoelectric coupled systems considering demand response. First, based on the framework of a typical thermoelectric coupling system, the energy hub equation of the system source load energy is established; second, the minimum system operating cost is selected as the optimization objective, and the transferable load participation ratio and the convertible load participation ratio are the load side constraints. Conditions, to achieve the mathematical modeling of the system; finally, the results of the calculation example show that the total cost of the system is reduced by 35.7% at the high transferable load participation ratio and the low convertible load participation ratio, and the optimal energy consumption of the thermoelectric coupling system is realized.
