Looped network cost pricing method and device based on power utilization reliability

Abstract

The invention discloses a looped network cost pricing method and device based on power utilization reliability. The method includes: combining basic electricity price, construct a cost pricing model according to the local side standby electricity price generated for the standby capacity cost in the residual capacity of the line and the opposite side standby electricity price generated for the standby capacity cost reserved for the user of the local side line in the residual capacity of the opposite side line; setting an excitation factor according to the total power supply demand, and reducing the pricing cost of the looped network when the real-time load of the line is smaller than or equal to the product of the excitation factor and the maximum historical load of the line; when the real-time load of the line is greater than the product of the excitation factor and the maximum value of the historical load of the line, performing pricing by adopting the average cost electricity price of a stamp method; and setting a standby margin according to the line reliability requirement, and when the total standby of the looped network is greater than or equal to the standby margin, increasing the pricing cost of the looped network to obtain a final user looped network cost electricity price pricing scheme, so that the pricing method provided by the invention is used for adjusting the electricity price through guidance for the electricity behavior.

Description

Technical field [0001] The present application relates to the field of electricity market technology, and more particularly to a loop cost pricing method and apparatus based on electricity reliability. Background technique [0002] In the electric spot market currently gradually reform, electricity price is no longer limited by the State Council, which should be generated in the game between direct purchase and power plants, with different regional characteristics and user needs. The transaction price should be different. At this point, the power trading market requires a reasonable pricing method to discuss how to determine the minimum supply cost recycling electricity price to ensure that it has sufficient capacity to fulfill the demand for market-oriented reform while fulfilling their power. [0003] In the power main network part, it is currently exploring the node marginal pricing algorithm based on trend change, and is used in the transaction settlement between direct purch...

Problems solved by technology

[0005] This application provides a ring network cost pricing method and device based on the reliability of electricity consumption, which solves the problem that the average pricing method cannot reflect the difference in user electricity prices, the simple pricing method cannot guide user electricity consumption behavior, and the utilization rate of equipment assets in the distribution network is low. , the adjustment of the ring network mode and the incremental construction of the power grid require warning signals
