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.

This paper briefly review the history of spot pricing theory and optimal power flow.

In order to ensure the successful introduction to a spot pricing scheme, it is essential to include accurate load-price elasticity models in optimal power flow (OPF) based marginal cost calculation methodologies.

The basic field of spot pricing in electric power market is outlined.

The model first draws on the nonlinear approaching capacity of the RBF network to forecast the load on the prediction day which takes no account of the factor of electric price, and then, based on the recent changes of real-time price, uses the ANFIS system to modify the resul.

Through implement of MBO in the past,it has exposed a lot of question,such as purchasing main part,purchasing price,purchasing fund hazard.

The increase of purchasing price for peasants farming initiative has been considered as an effective way to solve these in problems in agriculture.
