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

 I. INTRODUCTIONECENTLY and during the current and last decades, electronic equipment and devices are spreadly used. These are sensitive to electrical supply voltage disturbances. Also, with the extensive penetration of renewable energy sources in electrical systems, power quality becomes an important issue.Voltage sag is a common disturbance caused due to the reclosers to clear non-permanent faults [1].The voltage sag location in the electrical system is crucial in choosing and developing of voltage sag mitigation strategy. The different methods for improving power quality should be evaluated as cost and the expected achieved performance improvements it provides. With the costs of the different voltage sag mitigation methods and the expected benefits, a study of the various mitigation scenarios yields to a better quick return for the investment [2].Mitigating devices and the integration of DG in the electrical distribution system has an impact on the power flow
