目前的发电权交易主要是基于发电成本报价，虽在一定程度上可促使能耗低的机组获得更多的发电权，但无法保证实现预期的减排目标。此外，发电权交易没有考虑预留安全裕度，存在一定的运行风险。为解决上述问题，本文提出一种发电权交易模型。该模型以设定的减排目标为约束，在满足系统安全运行和电压稳定裕度的条件下，实现系统总有功出力最小。所提模型满足系统在经济性、环保性和稳定性方面的要求。采用基于约束松弛变量策略的中心校正内点法对所提模型进行求解，并在IEEE30、39、57和118节点系统验证了上述方法的正确性和有效性。

Although current generation right transaction, which is mainly based on the bidding of the generation cost, can make the generating units with low energy consumption achieve more generation right, however the implementation of the prospective emission reduction target cannot be ensured. Besides, in generation right transaction the security margin is not pre-set aside, so there is a certain operational risk. In allusion to this, a generation transaction model, in which the preset emission reduction is taken as the constraint and under the premise of ensuring the secure operation and voltage stability of power system the minimized total active power output of power system is taken as the objective, is proposed. The proposed model can meet the demand of power system in the aspects of economy, environment protection and operational stability. The proposed model is solved by constraint slack variable based centrality correction interior point algorithm, and the correctness and effectiveness of the proposed method are validated by simulation results of IEEE 30-bus system, IEEE 39-bus system, IEEE 57-bus system and IEEE 118-bus system.
