摘要

合理配置风光储容量是实现新能源高效利用与负荷稳定运行的基础。针对“双碳”目标下要构建以新能源为主体的新型电力系统的目标，提出了一种基于机组出力特征解析的风光储联合规划方法。首先，通过分析电力系统源-荷长时间尺度运行特性，揭示源-荷的一般运行规律，建立了机组时序出力比模型，解析机组出力特征；其次，进一步构建了基于机组出力特征解析的风光储联合规划模型，科学配置高比例新能源接入电力系统背景下的风光储容量；再次，设计了针对规划结果优劣性的源-储容量配比综合评价体系，从电力平衡、新能源消纳、碳减排3个方面对规划结果进行了综合评价；最后，以某大区电网为例进行了仿真。结果表明，所建模型能够基于对机组出力特征的解析配置出合理的风光储容量。

Abstract

Rational allocation of wind power

photovoltaic and energy storage capacity is the basis for efficient utilization of new energy and stable operation of loads. Aiming at the goal of building a new power system with new energy as the main body under the “double carbon” target

a joint planning method for wind power

photovoltaic and energy storage based on the analysis of output characteristics of power units is proposed. Firstly

by analyzing the long-term operation characteristics of the power system source-load

the general operation law of source-load is revealed

the unit timing output ratio model is established

and the output characteristics of the unit are analyzed. In addition

a joint planning model of wind power

photovoltaic and energy storage capacity based on the analysis of unit output characteristics is further constructed

and the wind power

photovoltaic and energy storage capacity under the background of high proportion of new energy access to the power system is scientifically configured.Moreover

a comprehensive evaluation system for the ratio of source-storage capacity to the advantages and disadvantages of planning results is designed

and the planning results are comprehensively evaluated from the aspects of power balance

new energy consumption

and carbon emission reduction. Finally

simlation is carried out by taking a large regional power grid as an example. The results show that

the proposed model can allocate reasonable wind power

photovoltaic and energy storage capacity based on the analysis of the output characteristics of power units.
