It has great significance to estimate the schedulable capacity of air-conditioning load of public building for participating the power network regulation by forecasting the air-conditioning load accurately. A novel forecast method considering the accumulated temperature effect is proposed in this paper based on Elman neural network.

An incremental load model during peak load period in which both load rate and simultaneity of load is given. To mitigate the influence of irregular putting into operation of transmission and distribution equipment on fluctuation of marginal cost of transmission and distribution, an annuity calculation method of average incremental cost is proposed, and a calculation model based on long-term marginal cost, which can rationally share the expense of voltage classes, is built.
