Research on Energy Effectiveness Evaluation Method of Micro–grid Energy Management System Operation Based on Multi–index Normalization Strategy

To address the problem of strong personalization of micro-network energy management demand, the variety of micro-network energy management strategies, and the lack of a set of evaluation mechanisms to assess whether a certain energy management strategy is suitable for the needs of micro-networks, this paper proposes a micro-network energy management operational effectiveness evaluation method based on a multi-indicator normalization strategy, which divides multiple indicators of micro-network energy management concern into three categories: direct normalization, inverse normalization, and absolute value normalization, and divides The positive contributions of each index are unified into a linear summation. Then the weight coefficients of each indicator are determined according to the individual requirements of the microgrid. Finally, we verify the effectiveness and practicality of this normalization strategy through an arithmetic example analysis.
