Standby and peak shaving auxiliary service cost allocation method facilitating new energy grid-connected consumption

Abstract

The invention provides a standby and peak shaving auxiliary service cost allocation method facilitating new energy grid-connected consumption. The method comprises the steps that a target function and constraint conditions of a new energy grid-connected consumption model based on production simulation are determined; the standby auxiliary service cost spent after new energy grid connection is calculated; new energy wind turbine generator earnings are calculated; the standby auxiliary service allocated cost is calculated; the peak shaving auxiliary service allocated cost spent by wind power connection is calculated. According to the standby and peak shaving auxiliary service cost allocation method facilitating new energy grid-connected consumption, the consumption model taking the extra service cost spent by new energy grid connection into account is built, the standby and peak shaving auxiliary service cost spent by new energy in different situations is analyzed, and therefore the allocation scheme for the auxiliary service cost spent after new energy grid connection is provided; service providing initiative of a traditional power source is effectively improved, the benefits of a provider are ensured, wind or light abandoning is reduced, and economical operation of a system is ensured.

Description

technical field [0001] The invention relates to an apportionment method, in particular to a cost apportionment method for back-up and peak-shaving auxiliary services that promote grid-connected consumption of new energy. Background technique [0002] my country's wind power development presents the characteristics of fast development, large-scale wind farms, long transmission distances, high transmission voltage, and being at the end of the power grid. Because areas rich in wind energy resources in my country are far away from load centers, large-scale wind power generation cannot be consumed locally, and there are no corresponding auxiliary service incentives and other factors, which exacerbate the impact of wind power on the regional power grid's consumption capacity. serious. [0003] At this stage, many developed countries have successfully realized the unbundling of ancillary services and electric energy services, and opened up an efficient ancillary service market, whe...

Problems solved by technology

[0005] With the rapid development of new energy sources such as wind power and photovoltaics, the demand for system auxiliary services is increasing day by day, that is, other types of units in the power system are required to provide more auxiliary services. If the current auxiliary service management mechanism in my country is still implemented, the existing The compensation rules do not take into account the increase in demand for ancillary services caused by wind power and other similar new energy sources, and the cost of backup ancillary services is shared between the power generation sources of the entire network. Costs have eroded the reasonable interests of other types of units, so that traditional units are unwilling to bear backup for wind power, resulting in severe wind curtailment
