Research on the Operation Optimization of a Multi-energy Complementary System Considering the Staircase Carbon Trading Mechanism

为增加能源效益、改善设备运营的弹性,进一步降低系统运行的碳排放水平,提出一种低碳经济运作策略。首先,将多能互补系统接入碳交易市场,引入分层碳交易机制以引导系统控制碳排放;然后,将新能源发电机组接入多能互补系统,并且引入抽水蓄能系统和火电机组发电系统以辅助系统电力调度,从而增加新能源消纳能力;最后,根据预测负荷和各项机组的运行约束,使用cplex求解器求解出低碳运行调度策略。结果表明:在碳交易机制的影响下,可以通过改进运行策略降低系统的碳排放;引入抽水蓄能系统可以改进多能互补系统,从而提高新能源的消纳能力。

To enhance energy efficiency,improve operational flexibility of equipment,and further reduce the carbon emissions of the system operation,a low-carbon economic operation strategy was proposed.First,the multi-energy complementary system was integrated into the carbon trading market,and a hier-archical carbon trading mechanism was introduced to guide the system in controlling carbon emissions.Then,renewable energy generating units were integrated into the multi-energy complementary system,and a pumped storage system and thermal power generation system were introduced to assist in power dis-patching and increase the accommodation capacity for renewable energy.Finally,the cplex solver was used to derive a low-carbon operation scheduling strategy based on predicted loads and operational con-straints of various units.The results indicate that under the influence of the carbon trading mechanism,system carbon emissions can be reduced by optimizing operational strategies.Additionally,the pumped storage system can be introduced to improve the multi-energy complementary system,and to enhance the capacity of renewable energy accommodation.
