Research on Dispatching Operation Strategy of Integrated Energy Microgrid in the Context of Power Internet of Things

在电力物联网深化综合能源系统变革的背景下,物联网从技术层面为综合能源服务提供了新的驱动力,但对其面向更多元的能源生产与消费情景提出了更多要求。传统微网系统已经难以适应新形势下调节多能耦合,及精准预测调度的愿景。文中以综合能源系统为根基,提出面向电力物联网的综合能源微网框架。指出应用层面要实现经济优化调度、综合能源整体布局和能源交易。提出能源供应商面向市场的上、下两层迭代优化调度的新型策略。根据模型特点,上层是以综合能源供应商利润最大为目标函数的优化调度数学模型,采用MATLAB/CPLEX求解器求解。下层为能源市场出清的数学模型,采用粒子群算法求解。通过算例结果表明,综合能源市场能够寻优到最佳社会福利点,能源供应商能够合理分配、利用各能源设备,进一步验证了所提方法的实操性。

In the context of deepening the integrated energy system reform of the power Internet of Things,the Internet of Things provides a new driving force for the integrated energy services from the technical level,but it puts forward more requirements for more diverse energy production and consumption scenarios.The traditional microgrid system has been difficult to adapt to the vision of adjusting multi-energy coupling and accurately predicting scheduling under the new situation.In this paper,the integrated energy system is taken as the base,the integrated energy microgrid framework for the power Internet of Things is proposed.It is pointed out that it is necessary at the application level to achieve economic optimization dispatch,overall layout of the integrated energy and energy trading.The new strategy of iterative optimization and scheduling for energy suppliers facing the market at the upper and lower levels is proposed.According to the characteristics of the model,the upper layer is the optimal scheduling mathematical model with the maximum profit of the comprehensive energy supplier as the objective function,which is solved by the MATLAB/CPLEX solver.The lower layer is the mathematical model of the clearing of the energy market,which is solved by the particle swarm algorithm.It is shown through the results of calculation examples that the integrated energy market can find the best social welfare point,and energy suppliers can reasonably allocate and utilize various energy equipment,which verifies further the practicality of the proposed method.
