Abstract

Recently, the restructuring of electricity market and the development of technology have been enhancing the application of distributed generators (DGs) and renewable energy resources. Hence, the planning of distribution systems (PDS) for competitive electricity markets (CEMs) has encountered impacts which need to be investigated. This paper proposes a novel approach for optimazing distribution system planning in CEMs with the presence of DGs. The proposed model can determine equipment sizing and timeframe required for upgrading power network in order for utilities to purchase electric energy from electricity markets. Besides, the problems of DG system development (Optimal DG displacement, sizing, technology selection and installation period) in distribution planning to meet the demand growth will be solved. The model uses the objective function that minimizes the total cost of network (feeders and transformers) upgrading, new DGs installation, distribution systems operating, and electric energy purchasing from CEMs. The proposed model is tested using a 33 bus 22 kV radial feeder. The calculation is programmed in GAMS environment.

竞争电力市场配电系统规划的新模型

近年来，电力市场的结构调整和技术的发展促进了分布式发电机和可再生能源的应用。因此，竞争电力市场(CEMs)的配电系统(PDS)规划遇到了需要研究的影响。本文提出了一种新的配电系统规划优化方法。该模型可以确定电网升级所需的设备规模和时间框架，以便公用事业公司从电力市场购买电力。解决配电规划中DG系统发展问题(最优DG排量、规模、技术选择和安装周期)以满足需求增长。该模型使用的目标函数是使网络(馈线和变压器)升级、新dg安装、配电系统运行和从CEMs购买电能的总成本最小化。采用33母线22kv径向馈线对该模型进行了测试。在GAMS环境下编制了计算程序。
