Allocation of Optimal PMUs for Power System Observability Using PROMETHEE Approach

Phasor measurement units (PMUs) are becoming a vital device in wide-area monitoring, operation, and control. The allocation of PMU at each bus will make that directly observable. However, considering the high installation costs, it is not feasible to place bus. Thus, placing PMUs optimal locations extremely important. In this study, Preference Ranking Organization Method for Enrichment Evaluation (PROMETHEE)-based multi-criteria decision-making (MCDM) technique has been applied phasor with aim achieving full system observability. Along entire network observability, proposed approach provides maximum redundancy (MR) too. Unlike some previous popular MCDM techniques, obtains placement (OPP) solution without performing pruning operations. Different criterion formulated construct decision matrix (DM). This DM helps calculating net outranking flow (NOF) all buses during PROMETHEE approach. Based on NOF value, placed those buses. also considers inclusion zero injection (ZIBs). Further, cases such as single outage existence conventional measurements have considered while determining PMUs. algorithm demonstrated IEEE 14-bus, 30-bus, 57-bus, 118-bus systems, one Indian practical utility, i.e., Northern Regional Power Grid (NRPG) 246-bus system, larger Polish 2383-bus system. To prove effectiveness algorithm, compared existing techniques.
