Abstract

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
