Multi Attribute Decision Making

For Receiving-end AC system, DC location selection depends on its role in supporting the DC system and economy. This paper proposes a method based on multi-attribute decision making of receiving-end power grid DC location selection. First, the balance of power DC location selected by region; then select the optimal placement through multi-attribute decision making; finally checked by calculating the feasibility of the selected placement. Zha Lute DC Shandong receiving-end power grid placement choice proved the effectiveness of the proposed method.

Phase measurement unit (PMU) is the key equipment for electric power system, which has been used to monitor and control power grid. But it is too expensive to deploy on each bus. So, we need to investigate how to deploy PMU to satisfy our observation requirements with minimum PMU numbers. This problem is called the optimal PMU placement (OPP). In this paper, we employ differential evolution (DE) algorithm to solve the OPP problem. Our optimization target is to make the power grid completely observable with maximum redundancy and minimum number of PMU. The proposed method is tested on IEEE 14-bus system, IEEE 30-bus system and IEEE 57-bus system respectively with considering the zero injection.
