摘要:
      微能源系统是能源互联网发展应用的重要形式之一。微能源系统是一个多输入多输出系统,各类能源转换设备和存储设备构成系统输入和输出的耦合关系。各设备通常具有非线性工作特征,使其运行特性与设计点发生偏移。针对微能源系统输入/输出的非线性关系,考虑储能的接入,建立微能网变工况静态耦合模型和储能状态转移模型,通过输入能源的统一折合,定义系统综合能源消耗,并提出依据微增率安排能源转换设备出力的策略。最后,以一个包含光伏、配电变压器、天然气热电联供、热泵、电池储能、蓄热式电锅炉的系统对所建立模型进行了应用和验证。提出的考虑微能源系统变工况特性的通用模型,是微能源系统优化设计和运行的基础。
Abstract:
      Micro-energy system is one of the important forms for the development and application of Energy Internet. A micro-energy system is a multi-input and multi-output system with a coupling relationship constituted by energy conversion and storage devices. These devices usually have non-linear working characteristics, which means deviation from the design performance. A static coupling model is established considering the nonlinear relationship between the input and output of a multi-energy microgrid. At the same time, the state transfer equation for energy storage is given. The integrated energy consumption of the system is defined by unified input energy. And a load dispatch scheme of energy conversion devices based on incremental rate is proposed. Finally, the model is applied and validated in a system which includes photovoltaic, distribution transformer, combined heat power generation, heat pump, battery storage and regenerative electric boiler. The proposed general model considering off-design performance of devices provides the basis for optimal design and operation of micro-energy system.
