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 int

Embodiment Construction

[0076] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0077] Such as figure 1 , the present invention provides a backup and peak-shaving auxiliary service cost allocation method that promotes new energy grid-connected consumption, and the method includes the following steps:

[0078] Step 1: Determine the objective function and constraints of the new energy grid-connected consumption model based on production simulation;

[0079] Step 2: Calculate the backup ancillary service cost after new energy is connected to the grid;

[0080] Step 3: Calculate the income of new energy wind turbines;

[0081] Step 4: Calculating the allocated cost of backup ancillary services;

[0082] Step 5: Calculate the cost sharing of peak shaving auxiliary services caused by wind power access.

[0083] In the step 1, the objective function of the new energy grid-connected consumption model based on production simulation is express...

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...
