Optimal placement and control of BESS for a distribution system integrated with PV systems   저자 Kihara Hiroyuki, Yokoyama Akihiko, Liyanage Kithsiri M, Sakuma Hisato 학술지정보 The Journal of International Council on Electrical Engineering 발행정보 International council on electrical engineering 2011년 자료제공처 국회도서관 KISTI 국립중앙도서관 주제분야 공학 > 전기전자공학  <초록> Recently, photovoltaic generation (PV) has attracted a great attention as one of green power generations. Accordingly a large amount of PV systems will be installed in residential areas in the coming years. In such scenario, reverse power flow caused by PV in feeders may cause some problems such as voltage rise over upper limits in the distribution line, and the reverse power flow into the distribution substation. Battery energy storage system (BESS) is a promising option to solve the above both problems at the same time. However, the effect of BESS depends on location of BESS. Therefore, it is necessary to ...

주파수추종서비스 제공을 위한 다수 배터리전기저장장치(BESS)의 통합제어 전략 Integrated Control Strategy of Multiple BESS for providing Primary Frequency Control 저자명 유가람, 최우영, 국경수 문서유형   학술논문학술지전기학회논문지 65(7) 1169-1175 1975-8359 KCI 발행정보  대한전기학회 |2016년 |한국어 주제분야   공학 > 전기전자공학  서지링크   KISTI  ​ <초록> As an Increased penetration level of renewable resources has caused concerns about primary frequency response, an increase in BESS(Battery Energy Storage System) capacity has been expected because of its fast response to the disturbances in the power system. This paper proposes the Integrated Control Strategy of multiple BESS for effectively providing the primary frequency control in the bulk power systems by coordinating the response, SOC and its recovery of BESS. The proposed strategy prevents multiple BESS from providing exceeding response and keeps the balance between SOC of multiple BESS. In addition, It would recover the SOC of BESS efficiently. The effect...
