摘要
小型可变可再生能源(RES)在城市电力系统中的大规模发展带来了较大的动态不平衡,从而可能在惯性响应方面造成不稳定。因此,设置适当的备用容量(OR)来补偿RES发电和负荷需求之间的未预测不平衡,对于电力系统的安全至关重要。事实上,考虑到RES和负荷需求的预测不准确,有效计算和调度备用容量可以带来可观的成本减少。因此,为了促进城市微电网(MG)中的能源管理和系统优化,本研究开发了一种用户友好的工具用于能源管理系统和运营规划。该工具提供了一整套用户友好的图形界面,用于研究光伏(PV)和电池、负荷需求以及微型燃气轮机(MGTs)的详细信息。此外,这个能源管理系统允许系统操作员正确建模RES的不确定性。它还可以通过高效的信息系统和智能管理,帮助操作员进行次日能源管理。
The large-scale development of small-scale variable renewable energy sources(RES)in urban power systems introduces significant dynamic imbalances,potentially leading to instability in terms of inertia response.Therefore,setting appropriate operating reserves(OR)to compensate for unpredicted imbalances between RES generation and load demand is crucial for power system security.In fact,considering the inaccuracies in RES and load demand forecasts,effective calculation and scheduling of operating reserves can result in considerable cost reductions.Therefore,to facilitate energy management and system optimization in urban microgrids(MGs),this study develops a user-friendly tool for energy management systems and operational planning.The tool provides a comprehensive set of userfriendly graphical interfaces for studying detailed information on photovoltaic(PV)and battery systems,load demands,and micro gas turbines(MGTs).Additionally,this energy management system allows system operators to properly model the uncertainties associated with RES.It also aids operators in day-ahead energy management through efficient information systems and intelligent management.
