摘要
建设低碳园区是实现碳中和目标的重要内容,目前园区节能减排和低碳发展普遍停留在计划式、间歇式的以减少电能浪费为主要目标的阶段,难以促进新能源消纳和电力系统低碳化转型发展。为此,提出一种基于绿电指数的园区常态化低碳运行机制,首先提出绿电指数的评价指标,基于园区楼宇负荷与系统新能源出力的同时率对各时段低碳行为进行量化评价;然后考虑园区中可中断和具备储能特性的两类负荷,基于其弹性和概率分布特性实现动态分组聚合;最后建立基于绿电指数的园区低碳运行优化模型,通过负荷的精细化调节实现园区节能减排常态化。以上海地区某园区楼宇实测数据进行仿真,结果表明该低碳运行机制能够实现园区节能减碳,有效促进新能源消纳,推动园区低碳常态化、可持续的开展,并为电网提供更丰富的调节能力。
To build a low-carbon park is an important part of carbon neutrality.At present,the park is still in a planned and intermittent energy-saving stage to avoid wasting electric energy,which is difficult to promote the consumption of renewable energy and the low-carbon transformation of the power system.This paper proposes a normalized low-carbon operation scheme for the park based on green power index.First,the evaluation index of the green power index is proposed based on the simultaneous rate of park load and renewable energy output.As a result,the low-carbon benefits of energy-saving behaviors in each period are quantitatively evaluated.Then,the elastic model of these loads is established considering two kinds of loads with interruptible and energy storage characteristics,respectively,and the load is grouped based on elastic clustering and probability distribution.Finally,the optimization model of low-carbon operation for the park is proposed based on green power index to realize the park’s normalized low-carbon operation through fine-grained regulation.The measured data of buildings in a park in Shanghai are taken to perform the simulation,and the results show that the proposed operation scheme can achieve carbon reduction for the park,and promote the consumption of renewable energy as well as the normalization and sustainable carbon reduction in the park effectively.Besides,it also provides richer flexibility for power grids.
