Abstract :
With the process of electricity market-oriented, taking advantage of the capability of electricity generation of autonomous power plant, large-scale power consuming corporation can decrease electricity expenses and boost competence of the corporation. However, forecasting accuracy of load is low due to private characteristics of large-scale power consuming corporation, it is difficult to satisfy the requirement for economic dispatch. In this paper, gateway balance is defined, balance between electricity generation and electricity consumption of large-scale power consuming corporation are analyzed and mathematical model is built. Loss function is employed to reduce prediction error further and enhance ratio of gateway balance.
