Abstract

The significant increase in Distribution Generation (DG) technologies such as solar and wind can provide environmental and economic benefits. However, uncontrolled solar and wind penetration at distribution level can have adverse effects on the feeders, such as overleverage. On the other hand controlling DG output can reduce the benefits for the residential level DG operators. This paper proposes a methodology for controlling residential DG output while providing incentive for their participation. The control of residential level DG is based on the power-loss and node voltage. The proposed controller will maximize the real power output, will compensate the DG operator using the leveliazed cost of energy. Marginal Levelized Cost of Energy (MCLOE) is proposed in this work for PV modules using the concept of Levelized Cost of Energy in power system operations. The proposed method is able to minimize the electricity cost by using multi-objective optimized operation strategy for a distribution system with residential PVs. A case study is also presented to validate the feasibility of proposed methodology.
基于边际均衡成本的考虑光伏发电的配电系统优化运行
太阳能和风能等配电发电(DG)技术的显著增加可以提供环境和经济效益。然而,在配电水平上不受控制的太阳能和风能渗透可能对馈线产生不利影响,例如过度杠杆。另一方面,控制DG输出会降低居民级DG运营商的收益。本文提出了一种控制居民DG产出的方法,同时为他们的参与提供激励。住宅级DG的控制主要基于电网的损耗和节点电压。所提出的控制器将最大化实际功率输出,将补偿DG运营商使用的能源平准化成本。本研究利用电力系统运行中的平准化能源成本概念,提出了光伏组件的边际平准化能源成本(MCLOE)。该方法通过采用多目标优化运行策略,使住宅光伏配电系统的电力成本最小化。最后,通过实例分析验证了所提出方法的可行性。
