Low-carbon economic scheduling strategy for power system with concentrated solar power plant and wind power considering carbon trading

为保证系统在低碳环保的前提下兼顾风电消纳与经济运行,提出一种考虑碳交易机制的光热电站与风电系统低碳经济调度策略。从低碳技术与低碳政策2个角度出发,将低碳手段与市场机制相结合,搭建考虑碳交易的光热电站与风电系统运行框架,并分析其运行机理;以火电出力承担基荷,建立以综合成本最低为目标的低碳经济调度模型,统筹系统低碳性与经济性;采用西北电网实测数据并在改进的IEEE 30节点系统中进行仿真验证,仿真结果验证了所提策略可有效降低碳排量,提高风电消纳率并降低系统的综合成本。

To ensure that the low-carbon operation of power system can take the wind power accommodation and economic operation into account,a low-carbon economic scheduling strategy for power system with concentrated solar power plant and wind power considering carbon trading is proposed.From the perspectives of low-carbon technology and low-carbon policy,combined the low-carbon technology with market trading mechanism,the operation framework of power system with concentrated solar power plant and wind power that considers carbon trading mechanism is developed,and its operation mechanism is analyzed in detail.The base load is supplied by thermal power units,and a low-carbon scheduling model that minimizes the total operating cost is established to balance the low-carbon objective and the economic performance.The practical data of Northwest Power Grid of China is applied in the modified IEEE 30-bus system,and simulative results show that the proposed strategy effectively reduces carbon emissions and improves the wind power accommodation rate.In addition,the comprehensive operating cost of power system is reduced.
