本文提出了一个需求响应 (DR) 框架，它将热力学建筑模型与基于遗传算法 (GA) 的优化方法交织在一起。该框架基于两个不同的目标：净负荷最小化和电力成本最小化，利用可再生能源本地分布式发电 (DG-RES) 优化商业园区微电网内最终用户的供暖/制冷计划。预计未来 DG-RES 向区域配电网络的馈电可能会受到限制，因此 DG-RES 被视为可缩减资源。我们通过一个冷藏仓库和一座办公楼的案例研究来测试灾难恢复框架，该办公楼位于具有本地光伏发电的商业园区。结果显示了 DR 框架在利用最终用户站点热质量的灵活性方面的技术潜力，以便：（1）减少连接点的能量交换； （2）降低微电网终端用户的用电成本； (3) 在 DG-RES 向电网输出受到限制的情况下，提高 DG-RES 的本地利用率。这项工作的结果可以帮助最终用户和配电网络运营商降低能源成本和能源消耗。
This paper presents a demand response (DR) framework that intertwines thermodynamic building models with a genetic algorithm (GA)-based optimization method. The framework optimizes heating/cooling schedules of end-users inside a business park microgrid with local distributed generation from renewable energy sources (DG-RES) based on two separate objectives: net load minimization and electricity cost minimization. DG-RES is treated as a curtailable resource in anticipation of future scenarios where the infeed of DG-RES to the regional distribution network could be limited. We test the DR framework with a case study of a refrigerated warehouse and an office building located in a business park with local PV generation. Results show the technical potential of the DR framework in harnessing the flexibility of the thermal masses from end-user sites in order to: (1) reduce the energy exchange at the point of connection; (2) reduce the cost of electricity for the microgrid end-users; and (3) increase the local utilization of DG-RES in cases where DG-RES exports to the grid are restricted. The results of this work can aid end-users and distribution network operators to reduce energy costs and energy consumption.
