Capacity market expense apportionment settlement method and device

Abstract

The invention discloses a capacity market expense apportionment settlement method and device. the unified purchase cost of each month of the capacity market is calculated; the ratio of the neutral standard capacities of the units in the capacity market is determined; calculating monthly purchase expenses of the group; In addition, other aspects are provided, wherein the system load in each month is three days at most; according to the proportion of the peak load average value of the average value of the power consumption load of each user or the power selling company in three days of the highest monthly system load, calculating the capacity cost needing to be shared by each user or an electricity selling company in each month; when the use amount load of each user or electricity selling company at the peak load moment of three days at most of the system load is too high; the higher the capacity cost needing to be shared by each user or electricity selling company is; The technical problems that according to an existing mode, due to inaccurate load prediction, the capacity cost sharing is not fair, an electricity selling company or a user cannot be effectively stimulated to reduce electricity consumption in the peak period of system load, the peak-valley difference of a system cannot be reduced, and the power generation capacity utilization rate cannot be increased are solved.

Description

technical field [0001] The invention relates to the technical field of electric power market, in particular to a method and device for sharing and settlement of capacity market expenses. Background technique [0002] With the advancement of electricity market reform, the construction of electricity spot market is gradually put on the agenda. In the electricity spot market environment, how to maintain the reliability of the long-term power generation capacity of the power system is an important issue. To solve this problem, establishing a capacity market is a feasible and effective method. PJM, New York State, New England and the United Kingdom have all established electric capacity markets. [0003] The general idea of ​​capacity market construction is similar. The market operator purchases the target power capacity uniformly according to the load forecast value of the target year, and then distributes the capacity purchase cost to users or load service providers (power sal...

AI Technical Summary

Problems solved by technology

[0005] The present invention provides a method and device for capacity market cost allocation and settlement, which solves the problem of unfairness in capacity cost allocation caused by inaccurate load forecasting in the existing methods, and can not effectively motivate electricity sales companies or users in the system load The technical problem of reducing power consumption during peak periods, reducing system peak-to-valley differences, and improving power generation capacity utilization
