摘　　要：混合电力市场中联营体与双边合同两类交易之间的调度会互相影响,为了更好地协调调度这两类电力交易,引入一个协调调度约束,提出了一个新的混合市场阻塞协调调度数学模型,该协调约束能够直观地处理系统中两类交易的优先性.此外,模型允许在联营体市场中对被削减的合同出力进行再调度,有利于降低联营体市场的购电成本.算例分析验证了所提出的模型的有效性.In the existing hybrid electricity markets, the pool and the bilateral-contract trades commonly interfere with each other. In order to effectively coordinate and dispatch these two trade modes, a coordinated congestiondispatching model for pool-bilateral markets by introducing a coordinated constraint to deal with the priority of the two trades. In this model, the curtailed generation of contracts is allowed to re-dispatch in the pool market, thus decreasing the purchasing cost of pool trade. Case study indicates that the proposed model is effective.
