基于熵值模糊层次分析法的碳化硅负荷接入位置对电网影响评估

高载能负荷参与需求侧响应已成为促进新能源消纳的重要举措,未来新型电力系统面临新能源占比不断提高及高载能负荷大规模接入的情况。亟需研究高载能负荷大规模接入对电网影响,以合理规划新能源机组与高载能负荷在配电网中的位置与容量。为此,以碳化硅负荷为研究对象,基于Matlab/Simulink仿真平台构建含高比例风电的IEEE33节点系统。基于参数摄动法,从电能质量、技术经济性、安全性3个方面评估风电机组与碳化硅负荷不同接入位置对电网的影响。应用熵值模糊层次分析法对仿真结果进行综合评估；评估结果与理论分析一致,验证了熵值模糊层次分析法的有效性。

Evaluation of the impact of silicon carbide load connection location on the power grid based on entropy fuzzy analytic hierarchy process

The participation of high-energy load in demand side response has become an important measure to promote the consumption of new energy. In the future, the new power system will face the situation of increasing the proportion of new energy and large-scale access of high-energy load. It is urgent to study the impact of large-scale access of high-energy load on the power grid, so as to reasonably plan the location and capacity of new energy units and high-energy load in the distribution network. Therefore, silicon carbide load is taken as the research object, and an IEEE33 node system with high proportion of wind power is built based on MATLAB/Simulink simulation platform.Based on the parameter perturbation method, the impact of different access locations of wind turbines and silicon carbide loads on the power grid is evaluated from three aspects of power quality, technical economy and safety. The entropy fuzzy analytic hierarchy process is used to evaluate the simulation results；The evaluation results are consistent with the theoretical analysis, which verifies the effectiveness of entropy fuzzy analytic hierarchy process.
