摘要/Abstract

摘要：

在低碳绿色经济背景下,为促进电力行业节能减排和绿色发展,将碳排放交易机制和绿色证书交易机制引入电力系统环境经济调度中,建立一个以绿色证书交易成本、火电发电成本、风电运行维护成本、弃风惩罚成本和碳交易成本为经济成本目标函数,SO₂和NO_x气体排放为污染物的含风电电力系统多目标环境经济调度模型。基于MOEA/D算法进行改进得出MOEA/D-OLSMS算法,采用MOEA/D-OLSMS算法与MOEA/D算法对模型进行求解。分析在不同调度情景以及不同可再生能源配额系数对系统的影响。通过算例仿真,验证所提出模型的有效性及算法的优越性。

Abstract:

In the context of low-carbon green economy, in order to promote energy conservation, emission reduction and green development of power industry, carbon emission trading mechanism and green certificate trading mechanism are introduced into the environmental economic dispatch（EED） of power system. Based on the objective function attempting to minimize green certificate transaction cost, thermal power generation cost, wind power operation and maintenance cost, wind power curtailment penalty and carbon emission right transaction cost, and taking SO₂ and NO_x emissions as pollutant emissions, a multi-objective environmental economic dispatch model for the power system containing wind power is established. By improving the MOEA/D algorithm, the MOEA/D-OLSMS algorithm is obtained.The model is solved by MOEA/D-OLSMS and MOEA/D algorithm,respectively. The impact of different renewable energy quota coefficients on the power system under different dispatch scenarios is analyzed. The validity of the proposed model and the superiority of the algorithms are verified by the simulation examples.

Key words: carbon emission trading mechanism, green certificate trading mechanism, environmental economic dispatch, multi-target, renewable energy quota, carbon neutrality
