摘要

针对含分布式可再生能源的热电联供综合能源系统，提出一种基于虚拟储能技术的热电联供综合能源系统联络线功率波动平抑策略。分析了综合能源系统中热电联供系统的结构特点与电热耦合方式。热电联供综合能源系统中的可控设备包括微型燃气轮机、热泵、蓄电池和超级电容。虚拟储能系统是基于建筑物蓄热特性的模型。引入可控设备及虚拟储能系统状态指标，采用加权滑动平均滤波算法确定联络线目标平滑功率；将联络线波动功率在可控设备间分配，并基于设备状态映射表，引入设备修正系数以确定其最终出力。在上海某高校"中意绿色能源实验中心"进行验证，结果表明，所提策略能够实现电热耦合协调，保证功率波动平抑效果，在满足虚拟储能状态约束的前提下，保证客户的舒适度，延长可控设备的使用寿命，并充分发掘热电联供综合能源系统的控制灵活性，增强分布式可再生能源的综合消纳能力。

Abstract

A coordination strategy was proposed to smooth the tie-line power fluctuation of the combined heating and power integrated energy system (CMPIES) by using the virtual energy storage system. The structure and energy coupling mode of the CMPIES were analyzed. The controllable devices in CMPIES include micro-gas turbines

heat pumps

batteries and super capacitors. Virtual energy storage system is a thermal model based on utilizing the heat storage characteristics of building. Considering the controllable devices and the virtual energy storage system state index

weighted moving average filtering algorithm was used to optimize the tie-line reference power. The coordination strategy designs state map table to regulate the filter time constant based on the operation state of the controllable devices. The output of controllable devices is adjusted by the correction factor calculated by the state map table. The proposed strategy was validated by the field data from Green Energy University Laboratory in China. The simulation shows the strategy realizes the coupling and coordination between power and heat

ensures the power fluctuation smoothing effect and enhance the CMPIES control flexibility. At the same time

the comfort of the customers participating in the CMPIES can be maintained. The coordination strategy is able to enhance the penetration and consummation of distribution renewable energies and prolong the controllable devices' life.
