Based on the arrangement principle of energy-saving generation dispatching, restricted by the security operation for the power grid, synthetically considering the factors of market and policy, the price of real-time purchasing electricity for the power grid is accurately calculated and analyzed. With the introduction of calculation for the marginal cost of purchasing electricity, an integrated decision-making model is proposed with the objective of minimizing energy consumption under the realtime generation adjustment for the power grid, which can be used to evaluate the economy of the trans-provincial or trans-regional electric power short-term trade of the electricity consumption. Meanwhile, the paper describes in detail the structure and main functions of the power grid real-time purchasing electricity price analysis calculation system, and shows the innovation of the system marginal cost of real-time purchasing electricity calculation and the practical features in automatic data optimization and system maintenance-free. The system proposed has already been applied into Sichuan power grid and the results show the practicality and effectiveness of the system.
