摘要

针对新能源汇集区域多储能系统在单一应用场景下储能利用率不高、汇集系统整体经济性较差的问题，考虑新能源跟踪计划误差分布特性和汇集区域电网净负荷峰谷特性，让储能协助新能源跟踪发电计划的同时辅助系统调峰。根据新能源出力特性和负荷功率特征，将储能运行区域划分为调峰区、跟踪计划区及荷电状态(states of charge，SOC)优化区，并提出一种面向发电计划跟踪与调峰的汇集系统储能分区协调优化运行策略。考虑新能源调峰成本分摊，跟踪计划误差惩罚，储能循环寿命成本、储能充放电转换成本等因素，针对不同区域分别建立储能优化运行模型。构建汇集系统整体跟踪计划出力效果评价指标、储能辅助系统调峰评价指标以及储能系统SOC评价指标，针对汇集系统优化运行结果进行评价。仿真结果表明，所提策略可以有效提升新能源跟踪计划出力能力，缓解系统调峰压力，降低新能源汇集系统整体运行成本，保证储能后续动作的可持续性。

Abstract

In response to the issues of low energy storage utilization rate and poor overall economic efficiency of multiple energy storage systems in a single application scenario in the new energy gathering area

the peak valley characteristics of the net load of the power grid as well as the error distribution characteristics of the new energy tracking plan are taken into account. In this context

energy storage can assist the system in peak shaving while aligning with the power generation plan. The energy storage operation area is divided into peak shaving area

tracking planning area and states of charge (SOC) optimization area based on the output characteristics and load power characteristics of the new energy. A coordinated and optimized operation strategy for energy storage zones in a centralized system is proposed for power generation plan tracking and peak shaving. Then

considering the factors such as new energy peak shaving cost allocation

tracking plan error penalty

energy storage cycle life cost

and energy storage charging and discharging conversion cost

the energy storage optimization operation models for different regions are established respectively

Indicators for overall tracking plan output effect evaluation of the collection system

peak shaving evaluation of the energy storage auxiliary system

as well as SOC evaluation of the energy storage system

are provided. Additionally

the optimization operation results of the collection system are assessed. The simulation results demonstrate that the proposed strategy can effectively enhance the output capacity of the new energy tracking plan

alleviate the peak shaving pressure of the system

reduce the overall operating cost of the new energy collection system

and ensure the sustainability of subsequent energy storage actions.
