Title (EN) MICROGRID SYSTEM, AND METHOD FOR MANAGING MALFUNCTION
(FR) SYSTÈME DE MICRORÉSEAU ET PROCÉDÉ DE GESTION DE DYSFONCTIONNEMENT
(KO) 마이크로그리드 시스템 및 고장 처리 방법
Abstract:
(EN) A microgrid system, which is provided with a plurality of decentralized power sources, a plurality of decentralized subordinates, and paths connecting the decentralized power sources and subordinates, according to the present invention may comprise: an ESS for storing power supplied from a part or all of the decentralized power sources, and providing the stored power to a part or all of the decentralized subordinates; an ESS PCS for converting the power stored in the ESS to alternating current power appropriate for the microgrid and supplying thereto, and equipped with a cut-off means for cutting off the connection to the microgrid in abnormal situations; and a control apparatus, when a malfunction is sensed in the microgrid, for gradually increasing the voltage outputted from the ESS PCS and managing the malfunction.
(FR) La présente invention concerne un système de microréseau qui comprend une pluralité de sources d'alimentation décentralisées et une pluralité de subordonnés décentralisés, ainsi que des chemins connectant les sources d'alimentation décentralisées et les subordonnés. Selon l'invention, ce système peut comprendre un ESS pour stocker la puissance fournie par une partie ou la totalité des sources d'alimentation décentralisées et pour fournir la puissance stockée à une partie ou la totalité des subordonnés, un PCS d'ESS pour convertir la puissance stockée dans l'ESS en une puissance de courant alternatif appropriée pour le microréseau et la fournir à celui-ci, ce PCS comprenant un moyen de coupure pour couper la connexion au microréseau dans des situations anormales, ainsi qu'un appareil de commande qui, lorsqu'un dysfonctionnement est détecté dans le microréseau, peut augmenter progressivement la tension fournie par le PCS d'ESS et gérer le dysfonctionnement.
(KO) 본 발명의 마이크로그리드 시스템은, 다수의 분산 전원들; 다수의 분산 부하들; 상기 분산 전원들 및 분산 부하들을 연결하는 선로들을 구비하는 마이크로그리드 시스템에 있어서, 상기 분산 전원들의 전부 또는 일부에서 공급되는 전력을 저장하고, 상기 분산 부하들의 전부 또는 일부로 저장된 전력을 제공하는 ESS; 상기 ESS에 저장된 전력을 상기 마이크로그리드에 적합한 교류 전력으로 변환하여 상기 마이크로그리드에 공급하되, 비정상 상황에서 상기 마이크로그리드와의 연결을 차단하는 차단 수단을 구비하는 ESS PCS; 및 상기 마이크로그리드에서 고장을 감지하면, 상기 ESS PCS에서 출력되는 전압을 점진적으로 높이면서 상기 고장에 대한 처리를 수행하는 관제 장치를 포함할 수 있다.
