Design, management and comissioning of a utility connected microgrid based on IEC 61850

Abstract

Abstract-This paper presents an approach to microgrid automation. The microgrid is composed of three different nodes connected to the public electric grid, which are hardware emulated with back-to-back converters. The microgrid is a flexible and weather independent test bed for testing different control algorithms. The intelligence of the automation system is split in three hierarchical layers: the RMU layer, the iNode layer and the iSocket layer. Communications among iNode and iSockets are according IEC 61850 standard.The aims of the project is to comission a set of technologies and acquire experience in microgrid automation, IEC 61850 communications and power control algorithms in DER systems.Index Terms-DER systems, IEC 61850, wind power emulator, storage unit emulator, load emulator, back-to-back.

Metodologia para processo integrado de comissionamento em unidades industriais

“…O comissionamento é uma prática aplicada a diferentes sistemas, e alguns exemplos reportados na literatura são: sistemas de instrumentação com wireless (Costa et al, 2014), processo de refinaria com óleo pesado (Kemaloglu et al, 2009), plantas de tratamento de efluentes (Gikas, 2008) e sistemas conectados em uma microgrid com IEC 61850 (Ruiz-Alvarez et al, 2010).…”

Scope of electrical distribution system architecture considering the integration of renewable energy in large and small scale

“…The insertion of large power plants in the generation stage is studied in [29][30][31]. The main characteristic is the use of wide areas to locate photovoltaic panels and wind turbines to generate power from 50 MW until the value of GW.…”

“…The integration of DGs linked with storage closed to the user is proposed in ongoing projects. The use of photovoltaic panels is considered in [31], [34][35][36][37]. Hybrid energy considering wind turbines, photovoltaic panels and fuel cells is studied in [38][39][40][41][42][43][44][45].…”

Optimized Design and Coordinated Control for Stand-alone DC Micro-grid

“…제어 방법에 따른 분류로는 먼저 중앙제어기를 두고 구성요소들의 전력량을 실시간으로 측정하여 알고리즘 에 의해 시스템을 운용하는 방식으로, 전력량을 측정하 기위한 센서와 측정된 데이터를 중앙제어기로 전송하는 통신망을 필요로 한다 [3]- [4] . 고속 통신망을 사용함으로 인해 중앙에서 각 기기들의 정보를 신속하게 전달받아 원활한 운용이 가능하지만 분산전원을 이용하는 경우 기후 예측 알고리즘이 필요하고 통신에 대한 의존도가 높으며 운용 알고리즘이 전력거래에 의존하게 되고 상 위 계통의 전력균형 유지에 집중하므로 계통연계 마이 크로그리드에 적합하다.…”
