Techno-Economic Assessment of Voltage Sags Mitigation in Distribution System Connected to DGs

The penetration of DG in electrical distribution systems has many benefits. paper highlights the impact at different load centers and operating conditions a feeder. on feeder voltage profile that depends size location system is illustrated. Mitigating methods are used to reduce effect disturbances. Economic assessment studies for assisting economic choice mitigating methods. Economical aspects connected DGs considered through analysis life cycle cost these generation sources. Maintenance strategies illustrated discussed keep sources always ready operation regarding minimization maintenance cost. Technical economical assessments depend availability historical data disturbances including damages disturbance mitigation using These difficult be available types loads. Therefore, indices, K1, K2, K3, proposed this loads as referring it reference overcome challenge shortage. Also, techno-economic index F device improving its feasibility. PSCAD/EMTDC simulation software package analysis. results show methodology facilitates decision choosing method power quality problems shortage assessment.
