“…But only flow measurement devices are considered here (by referring Ref. 14). The power, which flows in branch between buses i and j at i side is given by,

P_{i, j} - {jQ}_{i, j} = V_{i} I_{i, j} = V_{i} ((), V_{i} - V_{j}) y_{i, j}

where y i , j is admittance of the branch connecting bus i to bus j .…”

Summary Situational awareness of the electric power system is the need of the hour. This is in the wake of recent blackouts in various parts of the world. These blackouts could have been prevented with better telemetry and real‐time monitoring of power system states. A fast and reliable measuring system with devices optimally employed across the network shall enable reliable system operation. Faster situational awareness and visualization helps the system operator to take faster preventive measures and maintain system stability. Wide Area Monitoring System uses phasor measurement units (PMUs) to measure power system states. PMUs measure synchronously real‐time voltages at various buses and current phasors, which are flowing toward these buses. But, there is a need to optimally find the locations for installation of PMUs in the network for an observable system, with minimum investment. This optimal placement of PMUs (OPP) is a binary optimization problem, combinatorial in nature. In this paper, progress achieved until now in the field of OPP studies are consolidated. A discussion on the characteristics of problem formulations and shortcomings of methods and constraints considered has been done. Challenges have been highlighted to provide a good foundation for new researchers.

“…Os autores abordaram a alocaçãoótima de UMFs em condições de normais de operação e condição de contingência, porém não abordam a quantidade de canais das UMFs e não apresentaram a alocação do PDC. Dubey et al (2018) utilizam uma técnica de otimizacão chamada Evolução Diferencial para a localização das UMFs e PDCs, considerando a situação em caso de perda de UMF. Por fimé mostrado o custo relacionado com a instalação dos equipamentos.…”

“…Dentre deste contexto se insere o Sistema de Medição Fasorial Sincronizada (SMFS). (Dubey et al, 2018) Os SMFS são constituídos basicamente por Unidades de Medição Fasorial (UMFs) e por Concentradores de Dados Fasoriais (Babu e Bhattacharyya, 2016) . De acordo com Taher et al (2016), a UMFé considerada um dos mais importantes dispositivos de medição do sistema elétrico do futuro.…”

A Unidade de Medição Fasorial (UMF) é um equipamento que possibilita a medição sincronizada da tensão de sequência positiva e corrente dos sistemas elétricos em microssegundos. As UMFs são instaladas em subestações do sistema de energia e suas medições são enviadas e processadas pelo Concentrador de Dados Fasoriais, do inglês, Phasor Data Concentrator (PDC). Nos últimos anos, diferentes métodos para encontrar a alocação ótima das UMFs foram abordados na literatura. A contribuição desta pesquisa é, por meio de um Algoritmo Evolucionário, encontrar a alocação ótima simultânea das UMFs e PDCs, considerando a quantidade de canais das UMFs, a distância entre as UMFs e os PDCs e considerar a situação de observabilidade para contingência n-1. Com a metodologia proposta foi possivel encontrar a alocação das UMFs e PDCs para os sistemas de 14 e 30 barras do IEEE.

“…In this sense, the problem is modeled as a total cost minimization problem [4], taking into account both PMU and CI costs and using a genetic algorithm to confirm that the lowest total cost does not always correspond to the smallest number of PMUs. The paper [18] has a similar approach and proposes a multiobjective algorithm to address PMU, PDC and CI placement, simultaneously.…”

“…To be able to compare our results with related works, two cases (A and B) used in previous works are presented in Table 6, and used as input data for simulations. The same distance matrix is also assumed between buses from previous works, i.e., that all transmission lines have the same conductors 6,7,8,9,12,13,15,17,18,20,21,23,24,27,28,29,32,34,36,37,40,41,44,45,46,49,51,52,54,56,57,60,62,66,68,70,72,75,77,79,80,83,85,86,87,89,90,92,94,96,100,102,105,107,109,…”
