최근 전 세계적인 에너지위기에 따라 분산전원의 투입에 대한 관심이 갈수록 높아지고 있다. 하지만 분산전원의 계통투입은 필연적으로 소비자와 설비 측의 전압레벨과 전력조류흐름을 변화시킨다. 분산전원의 투입위치에 따라서 소비자와 설비 측의 전압은 크게 향상될 수 있으나 제한된 분산전원을 최적으로 배치하는 연구가 선행되어야 한다. 본 논문에서는 계통에 분산전원 투입할 시의 전압특성변화를 분석하고, 이를 토대로 계통의 전압품질향상을 목적으로 분산전원을 최적으로 투입하기 위한 알고리즘을 제안하였다.

Using DG for peak-shaving unit could reduce the overall system operating cost, and using DG for standby power unit could improve the reliability of the distribution system The models of peak-shaving unit and standby power unit are different from each other. The Monte-Carlo simulation is suitable for the purpose of the analysis of two DG models. In this paper, the reliability indices are calculated from the time-sequential method, and the merit and defect of the peak-shaving unit and standby power unit are investigated.

With Korean Government's Renewable energy 3020 plan and 8th Basic plan for long-term power supply, renewable energy industries in Korea are active and catching attention from many relevant industry's relations. Especially with Interconnection guarantee policy established in Oct, 2016, DERs interconnection delay due to lack of allowable distribution hosting capacity is happening and reduction of reinforcement cost for distribution system where 70 % of DERs in South Korea are installed became one of important issues of KEPCO. Therefore, KEPCO needed to extract reasonable solutions to increase feasible hosting capacity of distribution feeders in order to reduce reinforcement cost under the condition of no matter in distribution system operation. This paper proposes feasible hosting capacity of distribution feeders that can be adopted and the status of DER installation in distribution system, PV output data, minimum load in distribution feeders as well as capacity of distribution lines have been investigated and analyzed in proof of the proposal.
