Abstract

This paper investigates and quantifies the benefits and the cost of CO2 emissions abatement of a Micro Energy Community (MEC) in a tiny residential cluster of three houses in a Belgian context. A simulation-based comparative analysis is performed of two individual and two MEC concepts, i.e. a reference scenario, an individual electrification scenario, an electricity sharing scenario, and an energy community scenario. A deterministic dynamic white-box modelling approach, including optimal control, is used, considering heat for space heating and domestic hot water, and electricity for electrical appliances. The energy system that achieves the greatest emission reduction at the lowest cost, has a collective heat pump and a photovoltaic installation sized based on the plug load demand. This system reduces the annual CO2 emissions by 11.48 tons at a cost of 179 EUR/ton CO2 considering 2021 dynamic retail electricity prices with a median of 251 EUR/MWh and a fixed retail gas price of 64 EUR/MWh. However, the results are strongly dependent on the gas-electricity price ratio. The highest value of the retail gas price in 2021 leads to a negative CO2 emissions abatement cost of 154 EUR/ton CO2, putting energy community concepts on the radar for a cost-effective energy transition.

比利时微型能源社区的二氧化碳减排成本
本文研究并量化了微型能源社区(MEC)在比利时一个由三栋房屋组成的小型住宅群中减少二氧化碳排放的效益和成本。本文对两个个体和两个微型能源社区概念(即参考方案、个体电气化方案、电力共享方案和能源社区方案)进行了基于模拟的比较分析。采用了一种确定性动态白盒建模方法,包括最优控制,考虑了用于空间供暖和生活热水的热量以及用于电器的电力。该能源系统以最低的成本实现了最大的减排量,它包括一个集体热泵和一个根据插头负载需求确定大小的光伏装置。考虑到 2021 年动态零售电价(中位数为 251 欧元/兆瓦时)和固定零售天然气价格(64 欧元/兆瓦时),该系统每年可减少 11.48 吨二氧化碳排放,成本为 179 欧元/吨二氧化碳。然而,结果在很大程度上取决于气电价格比。2021 年天然气零售价格的最高值会导致 154 欧元/吨二氧化碳的负二氧化碳减排成本,从而使能源社区概念成为具有成本效益的能源转型的首选。
