摘要/Abstract

摘要：

针对工厂提出了一种以多能转供为核心的综合能源系统故障态运行策略。首先，基于可测参数对各供能设备进行建模，建立了综合能源系统模型。而后提出了各类供能设备出现故障时最大供能能力计算方法，得到各设备出力约束条件，并建立冷热电多种能源的功率及能量平衡方程。进而以运行费用最低为优化目标，采用线性规划法对目标函数进行求解。最后以某工厂综合能源系统为算例，分析了不同故障条件下采用该策略后各设备出力变化的合理性，结果发现该策略具有 3 个特点：低负荷时运行成本控制效果显著；本策略调控效果主要受分时能源价格影响；最大外购资源曲线具有预测故障后成本变化趋势的作用。

Abstract:

A fault-state operation strategy for integrated energy systems based on multi-energy transfer was proposed.Firstly,an integrated energy system model was built to model each energy-supply device in the system using actual measurable parameters.Then,the calculation method of maximum energy supply capacity when energy-supply device fails was introduced,and the power constraint conditions of each equipment were obtained,and the power balance equations of cold/heat/electricity power were established.Then,set the lowest operating cost as the optimization goal,the objective function was solved by the linear programming method.Finally,taking a factory-level integrated energy system as an example,the rationality of the output changes of each equipment after using this strategy under several fault conditions was analyzed.It is pointed out that the strategy has three characteristics:the cost control effect is significant at low load situation,remarkably impacted by time-sharing energy prices,the outsourcing resource curve can predict the change of operating costs when fault occurs.

Key words: integrated energy system, fault-state, multi-energy transfer, optimality of operation strategy
