The challenge of failure management emerges in decentralized architectures due to the distributed nature of the layered control process. Failures in microgrid system may occur at the microgrid level or any of the control layers. A failure detection and response mechanism is required to attain a reliable, fault-tolerant microgrid operation. This paper introduces a Failure Management Unit as an essential...
This paper introduces an automated and reconfigurable laboratory environment for rapid prototyping of DC and AC microgrids. The laboratory includes seven fully programmable power converters, 47.5 kWh lithium-ion battery, configurable AC loads, a set of AC busbars with configurable network impedances between them, a set of DC busbars and relevant monitoring and control equipment. Each laboratory element...
Energy management system (EMS) plays a crucial role in Microgrids. It is responsible for the power balance between generation and consumption. Different architectures for EMS are possible: the centralized, decentralized and hierarchical. The hierarchical is a good candidate to smooth the transition from the existing power management system to the Microgrid (MG) management configuration. Besides, multiagent...
This paper presents an optimized energy management system (OEMS) to control the microgrid of a remote temporary military base featuring the diesel generators, the battery energy storage system (BESS) and photovoltaic panels (PV). The information of the expected electric demand is suitably used to improve the sizing and management of the BESS. The OEMS includes power electronics to charge the batteries...
RSE's Distributed Energy Resources Test Facility has been included as active user in A2A Lambrate Smart Grid Project. The Test Facility control system makes possible to manage the various generation systems available, behaving as a unique controllable unit by the DSO. This activity allowed to test functions such as active and reactive power control, remote disconnection and fault detection, as well...
