New real-time heuristics for electrical load rebalancing in aircraft

Methodologies for the Synthesis of Reliable MEA Electrical Power System Architectures

“…Architectural options: MEA topology options [31], [32], system architecture for adaptability [33], power conversion modelling based on building blocks models [34], design simplification based on high level of abstraction simulation models [35]. Improvements of current electrical performance: reconfiguration and balancing problem in aircraft AC networks (Airbus operations) [36], weight saving optimized distribution system with modern concepts (Airbus operations) [37], optimization of energy-supply-structure of modern aircraft utilizing conventional power system technologies [38]. Exploration of new architectures: exploration of several HVDC-architectures for aircraft applications (Airbus operations) [32], Ptolemy II-Metropolis/Metro II tools for architectural explorations (IBM, UT, Bosch, NI, Toyota) [39], analysis of HVDC parallel electric power system for MEA [40].…”

“…Further to IDO, and RBDO approaches, there have been other contributions in optimizing existing EPS architectures in order to improve specific attributes. For instance, [36], [37] performed research to optimize current AC three-phase aircraft infrastructure, and also explored HVDC configurations for future MEA [32]. Although not adopting rigorous frameworks such as PBD or RBDO, these methodologies are still reliability-oriented.…”

Algorithm for the Optimal Design of a Fault-Tolerant Aircraft Power Transmission Network

“…According to this, current MEA's studies are catalogued into two main groups. The first group focuses on developing novel software for increasing aircrafts efficiency [21], [22]. The second group focuses on new feasible architectures to increase aircrafts' efficiency and safety of operation [23], [24].…”

Decentralized control and stability analysis for isolated microgrids

“…Driven by the demand to reduce gas emissions and decrease operational cost as well as to provide safe and comfortable services, the aircraft industry is moving towards more electric aircraft (MEA) [71,73]. MEA is to use electrical power to drive onboard loads, which are conventionally driven by a combination of hy- [78][79][80]. The interactions for such a complex system has not been reported in the literature.…”

“…A MODULAR APPROACH FOR STABILITY ANALYSIS OF MICROGRIDS required to ensure high reliability, stability and efficiency as well as light weight of MEA[72,73]. For example, the hybrid AC/DC architecture with 230V AC/360-800Hz and ±270V DC is adopted to the latest MEA platform Boeing B787[78,79].The MEA power system is a typical isolated MG with the extensive integration of CPLs[74]. It requires greater use of power electronic converters and motor drive systems for functions as flight control actuation, fuel pump, environmental control system, engine start, etc.…”
