| 中文摘要:我国电力现货市场建设处于初级阶段，单机组报价的竞价模式与级联发电机组的物理运行特性之间存在矛盾。当市场中所有发电机都独立进行价格申报及结算时，可能会使调度出清结果与实际机组群的运行性能相违背，由此给机组群报价带来困难，同时导致严重的调度偏差以及实际资源的浪费。文中针对级联水电机组等资源耦合的发电资源，提出了一种基于聚合节点的报价机制。首先详细介绍了聚合节点的报价机制及其报价策略；然后建立了聚合节点报价的现货市场出清模型；最后，通过IEEE5仿真算例证明了基于聚合节点的报价机制能够使得市场出清结果反映机组交易意愿，且有效地配置了级联水电发电资源，提高了电力现货市场的交易效率。 |

| Research on the Bidding Mechanism and Strategy of Cascaded Hydroelectric Units Based on Aggregation Nodes |
|
|
| Abstract:As China’s electric power spot market is at an initial stage， there exist contradictions between the bidding mode of single-unit quotation and the physical operating characteristics of cascaded generating units. When all generators in the market make price declarations and settlements independently， the dispatching and clearing results may be inconsistent with the operation performance of the actual unit group， which may bring difficulties to the unit group quotation， and lead to serious dispatching deviations and waste of actual resources. Therefore， for the power generation resources coupled with resources such as cascade hydropower units， this paper proposes a bidding mechanism based on aggregation nodes. First， the quotation mechanism and quotation strategy of the aggregation node are introduced in detail， and then the spot market clearing model of the aggregation node quotation is established. Finally， through the IEEE5 simulation， it is proved that the bidding mechanism based on the aggregation node can make the market clearing result reflect the generating units' intention to trade， effectively allocate cascade hydropower generation resources， and improve the transaction efficiency of power spot market. |
