Abstract: 

HARMONIC STATE ESTIMATION (HSE) OF POWER SYSTEMS IS A VERY EFFECTIVE AND ECONOMIC TOOL TO PROVIDE SYSTEM-WIDE SOLUTIONS FOR MONITORING OF HARMONIC POLLUTION IN THE POWER SYSTEMS. ONE OF THE BASIC PROBLEMS IN IMPLEMENTATION OF HARMONIC STATE ESTIMATION IS THE OPTIMAL NUMBER AND LOCATION OF HARMONIC METERS. IN THIS PAPER, A NEW METHOD FOR OPTIMAL ALLOCATION OF HARMONIC METERS IS PROPOSED. THE MAIN IDEA OF THE PROPOSED ALGORITHM IS THE USE OF SYSTEM ERROR COVARIANCE ANALYSIS PROVIDED BY KALMAN FILTER AND COMPARING THEM WITH EACH OTHER, FOR OPTIMAL ALLOCATION OF HARMONIC METERS, IN COMPLETELY-DETERMINED CONDITIONS. ALSO, METHOD OF POWER SYSTEM REDUCTION IS USED TO REDUCE THE COMPLEXITY OF CALCULATIONS AND TO IMPROVE THE ACCURACY OF THE RESULTS. THE COST FUNCTION IS DEFINED AS THE SUM OF INSTRUMENTATION COSTS AND THE COST CAUSED BY STATE ESTIMATION ERROR. GENETIC ALGORITHM (GA) IS ALSO USED FOR THE OPTIMIZATION PROBLEM. THE SIMULATION RESULTS FOR AN 18 BUS DISTRIBUTION SYSTEM SHOW THE EFFECTIVENESS OF THE PROPOSED ALGORITHM.
