摘要
电力市场双侧竞价交易中发电商和用户报价变化所导致的竞价电量波动将会引起电力系统中潮流重新分布,对安全运行产生影响。该文结合双边合同与双侧竞价并计及静态电压稳定裕度约束建立了交易模型,提出将连续潮流和最优潮流相结合,识别双方特定报价水平下网络中存在的薄弱环节,制定出既能实现社会效益最大化,又能保证系统安全运行的交易计划。IEEE30 节点系统算例结果表明该文模型和方法的正确性与有效性。
The power variation on the consumer side and the generation side caused by double auction may result in power flow’s redispatch and have disadvantageous effect on power system security operation. The mechanism of double auction in electricity market was analyzed and the double auction model involving voltage stability margin was set up in this paper. Continuation power flow and optimal power flow were combined to detect the transmission network vulnerable spot and make reasonable electricity trade plan. The proposed method can achieve the reliable operation of power system and maximize the social welfare. Results of IEEE 30-bus system show the model and method are valid.
