基于绿色证书交易的含风电系统低碳经济调度

摘要

为促进风电的发展,将绿色证书交易机制引入电力系统调度模型中,建立了基于绿色证书交易机制的含风电系统低碳经济调度.引入环境成本将系统的低碳目标和经济目标进行统一;引人风险成本以应对由风电出力不稳定性对系统带来的影响.采用细菌群体趋药性算法对所建模型进行了优化求解,对低碳经济调度与传统调度的结果进行了对比分析,并对不同的绿色证书交易水平对系统成本以及碳排放量的影响进行了分析 通过算例分析验证了本文所提模型的合理性和有效性.%In order to promote the development of wind power,the green certificate trading mechanism is introduced into the dispatching model of power system,and a low-carbon economic dispatching for power grid integrated with wind power system is established based on tradable green certificates.In this paper,the environmental cost is introduced to make the low-carbon objective and the economic objective unified.The cost of risk is introduced to cope with the influences of unstable wind power output on the power system.The bacterial colony chemotaxis algorithm (BCC) is used to make an optimization solution of the established model.The results of the low-carbon economic dispatching and the traditional dispatching model are compared and the impact of different green certificate trading levels on system cost and carbon emissions are analyzed.Case study has proved the effectiveness of the established model.
