“…Based on the context information and fol-lowing the IEC 61850 standard, distributed en-ergy resources (DER) are divided in two groups: Programmable DER (DER-P) and Not Pro-grammable DER (DER-NP) (Postigo and Silva, 2018). The battery energy storage system (BESS) and the combined head  Fault Operation: Whenever a fault is de-tected, the PCC switch opens, and micro-grid is separated from the service network and switches to Automatic Mode.…”

Helicopters are high cost and safety systems with a strong control system designed to maintain the helicopter performance, stability, and ight qualities. However, there exist faults that negatively a_ect the helicopter desirable behaviour; therefore, fault detection and isolation must be done to early detect, isolate and eliminate these faults. Because of helicopters are strongly nonlinear systems, and are a_ected by uncertainties and by external disturbances as wind bursts, robust residuals generation is required to correctly detect and isolate faults in the helicopter actuators and sensors. This paper leads with the robust fault detection and isolation of a six-degree of freedom helicopter benchmark using the disturbance decoupling method and the unknown input observer robust residuals generator. A generalized observer scheme is employed for fault isolation purposes.

“…Based on the context information and following the IEC 61850 standard, distributed energy resources (DER) are divided in two groups: Programmable DER (DER-P) and Not Programmable DER (DER-NP) (Postigo and Silva, 2018). The battery energy storage system (BESS) and the combined head and power (CHP) are part of the DER-P. On the other hand, natural sources like Photovoltaic system (PV) and Wind Power (WP) belong to DER-NP, due to the uncertainty of power generation and randomization in renewable energy production.…”

Microgrids appear as a practical, clean and reliable solution to meet the demand of populations that, for various reasons, do not have access to electricity. The complexity of microgrid systems, requires considerable engineering eort in the design process. To design this type of complex systems, new approaches, methods, concepts and engineering tools are needed. Where, the requirements analysis has a preponderant role to better characterize, understand and specify the application domain and the problem that the microgrids must solve. This work proposes the introduction of a formal analysis of requirements in the life cycle of microgrid systems, using IEC 61850 as a reference architecture. The requirements would be represented in an Object Oriented Requirements Engineering (GORE) approach, using specically visual diagrams based on the KAOS (Keep All Objectives Satised) method, where the operation and control of the network will be formally represented. The requirements analysis is presented using a combined representation that uses the GORE and Petri Nets methodology for dynamic modeling and formal verication. A case study for small communities in the Amazon rainforest is used as a case study for the proposed method.

“…Actually, for automated systems, formal representation and verification are key issues, leading to a cycle composed of modeling, formalization, and verification. Existing methods consider this cycle a preliminary stage, where the problem P is modeled after some refinements, leading to a model-based requirements approach [7][8][9].…”

A solid demand to integrate energy consumption and co-generation emerged worldwide, motivated, on one hand, by the need to diversify and enhance energy supply, and, one the other hand, by the pressure to attend to the requirements of a heterogeneous class of users. The coupling between energy service provision and final users also includes balancing user needs, eliminating excesses, and optimizing energy supply while avoiding blackouts. Another motivation is the challenge of having sustainable sources and many adapted to the user ecosystem. Altogether, these motivations lead to more abstract design approaches to co-generation-distributed systems, such as those based on goal-oriented requirements used to model smart grids. This work considers the available design practices and its difficulties in proposing a new method capable of producing a flexible requirement model that could serve for design and maintenance purposes. We suggest coupling the approach based on goal-oriented requirements with model-based engineering to support such a model. The expected result is a sound and flexible requirements model, including a model for the interaction with the final user (now being considered a producer and consumer simultaneously). A case study is presented, wherein a small energy service system in an isolated community in the Amazon rain forest was designed.
