【摘要】 我国区域性电力市场试点工作率先在华东地区展开 ,华东区域电力市场将采用 Broker现货市场加双边合同的结构。由于 Broker交易匹配法的常规交易计划方法在受网络约束的情况下不能获得最优经济效益 ,文中提出了直接考虑网络约束的交易计划新方法。通过引入发电贡献因子和负荷汲取因子解决了多级电力市场中存在的协调问题 ,并针对双边交易的特点 ,采用交易矩阵的方式建立了区域电力市场中 Broker系统制定交易计划的数学模型。在 IEEE 30节点系统上的计算结果表明 ,在不计网络约束的情况下 ,该模型符合 Broker交易模式的特点 ,而在考虑网络约束的情况下 ,用该模型可以取得最大的社会福利 ,从而验证了模型和算法的有效性。更多还原

【Abstract】 East China Regional Electricity Market, the first regional electricity market in China, will adopt the structure of Broker spot market combined with bilateral contracts. The conventional transaction scheduling method of using Broker matching algorithm cannot obtain optimal economic benefit with considering network constraints. This paper proposes a new transaction scheduling method of considering network constraints directly. With introducing the generation contribution factor and load extracting factor, the problem of coordination of multi level electricity market is solved. In consideration of the characteristic of bilateral transaction, a mathematical model is established for transaction scheduling in Broker trading system of regional electricity market with transaction matrix as a mathematical representation. The results of the test on IEEE 30 bus system show that the model corresponds with the features of Broker trading mode without considering network constraints, and can obtain optimal economic benefit with considering network constraints. The effectiveness of the method is proved.更多还原
