利用TRNSYS模拟仿真平台对该系统进行优化模拟。研究结果表明

与优化前系统容量相比

优化后系统中电热锅炉功率及蓄热水池容积都有所减小

虽然系统的余电消纳能力降低

但系统整体平准化供热成本CLCOH降低

光伏余电蓄热系统的经济性得到明显提升。

Abstract

This paper carries out a study on the optimal configuration of the photovoltaic residual electricity thermal conversion and heat storage system based on the energy system optimisation theory

it establishes a capacity optimisation model of the photovoltaic residual electricity thermal conversion and heat storage system with the goal of minimising the levelized cost of heat（LCOH）

and then simulates the optimisation of the system using the TRNSYS analogue simulation platform. The results show that

compared with the system capacity before optimisation

the power of the electric heating boiler and the volume of the water body in the optimised system are both reduced

and although the system's capacity for residual electricity utilization is reduced

the overall of the system is reduced

and the economy of the photovoltaic residual electricity thermal conversion and heat storage system has been significantly improved.
