摘要

为优化以清洁能源为主体的热电联供综合能源系统(integrated energy system，IES)，针对系统热电供需不匹配和绿电制氢经济效益不高的问题，提出一种考虑将燃气掺氢技术(hydrogen enriched compressed natural gas，HCNG)和光热发电(concentrating solar power，CSP)协同作用的优化调度模型。首先，对传统热电联供系统进行低碳化改造，将热电联产(combined heat and power，CHP)机组与燃气掺氢技术相结合，构建燃气掺氢热电联产机组的数学模型。其次，引入含有大容量储热系统的CSP电站，在此基础上，再结合余热回收装置和电加热器，构建考虑热回收的光热电站模型，实现CSP-CHP-HCNG协同运行。最后，以系统运行总成本最低作为优化目标，建立CSP-CHP-HCNG协同供能的IES优化调度模型。设置4种典型场景进行对比分析，并分析不同燃气掺氢比下系统内各设备的出力情况，证明该模型能有效促进新能源消纳，提高系统运行经济效益。

Abstract

To optimize the cogeneration integrated energy system (IES) with clean energy as the primary focus

an optimal scheduling model considering the synergistic effect of hydrogen enriched compressed natural gas (HCNG) and concentrating solar power (CSP) is proposed. This model aims to address the mismatch between supply and demand of thermoelectricity in the system

as well as the low economic benefits of green power hydrogen production. Firstly

the low-carbon transformation of the traditional cogeneration system is implemented

and the combined heat and power (CHP) unit is combined with the gas-mixed hydrogen technology to construct the mathematical model of the gas-mixed hydrogen cogeneration unit. Secondly

a CSP plant with a large-capacity thermal storage system is introduced. On this basis

by integrating a waste heat recovery device with an electric heater

a CSP model considering heat recovery is constructed to realize CSP-CHP-HCNG coordinated operation. Finally

an IES optimal scheduling model for CSP-CHP-HCNG collaborative energy supply is established

with the objective of minimizing the total operational cost of the system. By comparing four different scenarios and analyzing the output performance of each equipment under varying gas hydrogen blending ratios

it is proved that the model significantly promotes the consumption of new energy and improves the economic benefits of system operation.
