基于DG的零售电力市场中零售商最优电价和电量确定及社会福利最大化

Optimal Price and Quantity Determination of Retailer Electric Contract and maximizing social welfare in Retail Electrical Power Markets with DG

Barati Masoud, Nikkhah Mojdehi Mohammad, Kazemi Ahad

摘要:

零售电力营销商,也称为零售商,通常与供应商签订合同,一方面以固定价格获得电力,另一方面与最终用户签订合同,以商定的费率满足其负荷要求。此外,全球范围内分布式发电(DG)资源的高渗透率也越来越多。从零售商的角度出发,分析了在供应商和最终用户双方建立合同,以使分销系统的利润最大化,同时保持最小的运营成本的问题。所提出的两级最优化模型可以使含分布式电源的配电系统的成本最小化,零售商的利润最大化。基于IEEE 33节点试验配电网进行了数值模拟。测试结果显示所提出的方法的性能。

英文摘要:

Retail electrical power marketers, also known as retailers, typically set up contracts with suppliers to secure electricity at fixed prices on the one hand and with end users to meet their load requirements at agreed rates on the other hand. Also high penetration of distributed generation (DG) resource is increasingly observed worldwide. Considering the viewpoint of a retailer, this paper analyzes the problem of setting up contracts on both the supplier and end-user sides to maximize profits while maintaining a minimum operational cost of distribution system. The proposed two-level optimization models can minimize the cost of distribution system with Distributed Generation and maximize the profits of retailers. The numerical simulations are carried out based on an IEEE 33-bus test distribution network. Test results are included to show the performance of the proposed method.
