水电煤电协同发展促进电力系统低碳转型方案评价
Evaluation on low-carbon transformation scheme in power system promoted by coordinated development of hydropower and coal-fired power
摘要
Abstract
In order to coordinate the development of hydropower(pumped storage),actively plan the scale and timing of coal-fired power decommissioning,incorporate wind and solar resources,ensure the stable and low-carbon transition of the system,and explore the multi-index and multi-level comprehensive benefits in power system transformation(mainly considering hydropower development and coal-fired power development),taking the power system transformation plan of Xinjiang Uygur Autonomous Re-gion as an example,a power system unit commitment model was constructed by considering reservoir operation conditions and unit operation characteristics.Five transformation scenarios of basic decommissioning,hydropower transformation,coal-fired power transformation,increasing pumped storage and accelerating decommissioning were formulated by the regional development plan.The comprehensive evaluation index system of four dimensions of economy,environment,technology and society was established by combining the analytic hierarchy process-entropy weight method.The results showed that:① increasing pumped storage under the coordinated coal-electricity transformation could effectively reduce the abandoned amount of wind and solar electricity gener-ating and the load loss probability in the power system;②increasing pumped storage and rational planning of withdrawing coal-fired power wouldn't increase the annual cost of the power system,and could reduce the carbon emissions of the system;③ the comprehensive evaluation score of the accelerated decommissioning scenario was the highest,which was 71.53.The research re-sults can provide theoretical support for the construction of new power system,the development of hydropower(pumped storage),the decommissioning of coal power and the integration of wind and solar resources.关键词
