基于综合需求响应的工业园区联络线功率控制

为平抑可再生能源系统所引起的联络线功率波动,工业园区通常采取整合园区内部所有源荷设备进行统一集中管理或基于电力需求响应的简单源荷互动运行模式,未能充分挖掘园区多能负荷综合需求响应的潜力。在分析工业园区用能特点的基础上,文中提出了一种基于综合需求响应的联络线功率控制方法,建立了园区与生产任务相关的储能、空调负荷以及电动汽车的综合需求响应特性模型,并通过激励多元用户进行需求响应以平抑功率的波动,有效实现了兼顾综合运行成本及跟踪控制误差的联络线功率控制。结合南方某蓄电池生产工业园区进行算例分析,结果表明该方法能降低园区经济损失,使内部负荷用户受益,并确保对联络线功率计划的有效跟踪。

Tie-line power control method for an industrial park based on integrated demand response

In order to stabilize the power fluctuation of the tie line caused by the fluctuation of the renewable energy system, the integrated energy system of the industrial park usually adopts a unified and centralized management of all source and load equipment in the park or a source-load interactive operation control mode based on simple electricity demand response, which cannot be fully utilized the park''s diversified demand response program and the potential for inte-grated demand response. In this regard, this paper proposes a tie-line power control method based on the integrated demand response by fully analysis of the energy consumption characteristics and coupling relationships of the industri-al park. Firstly, an integrated demand response model of energy storage related to production tasks in the park, air conditioning load with room thermal inertia, and distributed electric vehicle load are established in detail. Then, based on the integrated demand response model of multiple loads, the users are incentivized to participate in tie line power fluctuation suppression, and the optimal tie-line power control scheme that minimizes both the error of tie-line track-ing control and operating cost is realized. Taking a battery production industrial park in the south as an example, the results show that the proposed method can not only reduce the economic loss of the industrial park, but also benefit the internal load users, and ensure the effective tracking of tie line power plan.
