高载能企业(EIE)是重要的工业负荷，且具有较好的可调节特性。将 EIE 纳入电力系统调度中不仅能够改善电力系统运行的经济性，还可以在适当的机制下减少 EIE 的用电成本。文中研究了 EIE 参与电力系统调度的相关问题。首先，建立了 EIE 的数学模型，以描述其运行特性和行为特性。然后，将该模型纳入到含安全约束的系统机组组合问题中；在此基础上，提出了集中式联合调度、分布式联合调度、单步协调调度等多种联合调度模式。最后，通过算例展示了联合调度的必要性，并横向对比了不同调度模式的效果；此外，还特别展示了联合调度在消纳大规模可再生能源时的效益。

Energy-intensive enterprises (EIEs) are important industrial loads,which have very good adjustment capability. Integrating EIEs into power system dispatch can not only improve the economic efficiency of the entire system,but also reduce the EIEs” electricity costs under certain mechanisms.The related issues of integrating EIEs into power system dispatch are analyzed,and the models are developed to describe the EIEs” operational and behavioral characteristics.Then the models are embedded into a security-constrained unit commitment model.On this basis,the three different dispatch modes,i.e., centralized coordinative dispatch,decomposed coordinative dispatch,and single-step coordinative dispatch,are proposed. Finally,the necessity of the coordinated dispatch is demonstrated,and the different coordination modes are compared via cases, while the benefits of coordinative dispatch are especially shown in helping accommodate large-scale renewable energy generation.
