考虑静态电压稳定的低碳电力调度

Low Carbon Generation Dispatch Considering Static Voltage Stability

为使低碳电力调度满足电网静态电压稳定性的要求,分析碳捕集系统对电厂上网功率的影响,并推导碳捕集系统运行功率的上、下限求解方法。在此基础上,提出一种考虑静态电压稳定的低碳调度模型,在满足电网运行和电压稳定裕度约束的条件下,使电厂发电和碳排放成本之和最小。所提模型以碳价为纽带,协调了调度方案在经济性、环保性和稳定性方面的不同要求,为控制二氧化碳的排放提供了一种可操作的方法。采用内点法对所提模型进行求解,并在IEEE30节点系统和某一实际系统上验证了所提方法的有效性。

To satisfy the requirement of static voltage stability in generation dispatch based on low carbon,the impact of carbon catch system（CCS） on power supply from plant to grid was analyzed,and the upper and lower bounds of the operating power for CCS was deduced.Based on this,a low carbon based generation dispatch model considering static voltage stability was proposed,whereby the sum of generation cost and CO2 emission cost can be minimized while satisfying the constraints of operation and voltage stability.The proposed model,which coordinated the requirements of economic,environment and stability for generation scheduling by taking the cost of CO2 emission as connective ties,offered a practical method for decreasing the emission of CO2.The proposed model was solved by interior point method.The effectiveness of the proposed method was validated in IEEE 30-bus system and a practical power system.
