提出了考虑电力系统池市场、双边市场和备用市场同时相互作用的定价模型。该模型可以在传统的边际定价（MP）或按出价定价（PAB）定价下工作。在PAB定价方法中，考虑到长期稳定的双边合同的存在，集成过程涉及到在池和储备市场中获得中标的交流最优潮流（OPF）。因此，能源和储备服务的价格包含了拓扑结构、电压等级、损耗、发电机和输电线路的容量限制的影响。结果表明，代理商可以根据价格来规划他们的投资组合，价格反映了在几种运营方案和投标策略下提供几种电力服务的影响以及相关的资源成本。从系统监管者的角度来看，PAB支付的最小化除了确保财政充分性外，还确保了能源供应、传输损失和准备金要求。给出了评价模型的数值实例。
A pricing model considering the simultaneous interaction of pool, bilateral and reserve markets in a power system is presented. The model is able to work under the classical marginal pricing (MP) or under the ldquopay-as-bidrdquo (PAB) pricing. In the PAB pricing approach, an integration process involves an AC optimal power flow (OPF) for obtaining awarded bids in the pool and reserve market considering the presence of long-term firm bilateral contracts. As a result, prices of energy and reserve services incorporate the influences of topology, voltage levels, losses, capacity limits of generators and transmission lines. Results show that agents can plan their portfolios based on prices reflecting the impact of supplying several electricity services and associated costs of resources in several operation scenarios and bid strategies. From the perspective of the system regulator, the minimization of payments by PAB ensures the supply of energy, transmission losses and reserve requirements besides enforcing financial adequacy. Numerical cases are presented for evaluating the model.
