| 工业园区微电网中动态工业生产流程与其能源供应是紧密联系的，通过灵活调控其工业生产流程的用能计划，参与到配电市场中，可进一步减少其用电成本。提出一种基于通用化生产流程模型的工业园区微电网参与配电市场的能量管理与生产流程协同优化模型与方法，并引入地源热泵进一步提高能效。首先，提出了含地源热泵的工业园区微电网的用能架构，建立了工业生产流程与用能关系的通用模型。其次，构建了基于通用化生产流程模型的工业园区微电网参与配电市场的双层优化模型，分别以工业园区微电网能量管理与生产流程调度协同优化模型为上层模型，以配电市场出清模型为下层模型，双层模型之间交换功率和电价信息。然后，基于KKT条件、对偶原理以及大M法将双层模型转化为混合整数二阶锥规划(mixed-integer second-order-cone programming, MISOCP)模型。最后，以短流程炼钢厂、水泥厂等典型工业园区为例进行算例分析。结果表明所提出方法可对工业生产流程进行有效建模，并降低工业用户的用能成本，缓解电网调峰压力。 |

| Abstract: |
| The energy supply of an industrial park microgrid and its dynamic production process are tightly coupled. By flexibly regulating the energy consumption plan and participating in the power distribution market, the cost of purchasing electricity can be further reduced. This paper presents an optimal model and method of energy management and collaborative scheduling of production processes in industrial park microgrids that participate in the power distribution market. The model is based on a generic production process model and incorporates ground source heat pumps to enhance energy efficiency. First, this paper proposes an energy consumption framework for an industrial park microgrid that uses ground source heat pumps. A general model is established to illustrate the relationship between industrial production processes and energy consumption. Then, a bi-level energy management model based on the generic production process model is constructed to participate in the power distribution market. The industrial park microgrid energy management and production process scheduling collaborative optimization model is the upper model, and the distribution market clearing model is the lower model. Power and price information are exchanged between the bi-level models. Next, based on the KKT conditions, duality principle and large M method, the bi-level model is transformed into a mixed-integer second-order cone programming (MISOCP) model. Finally, taking a short-process steel plant, a cement plant and other typical industrial parks as examples for case studies, the results show that the proposed method can effectively model the industrial production process, reduce the energy cost of industrial users, and relieve the pressure of power grid peak regulation. |
