“…In different flight stages, the loads change, thus the optimal EPS configures power contactors on/off status, and the power flowing through each components to achieve a more efficient topology to reduce total power demand from generators. Therefore, the objective function for this problem formulation can be expressed as (12), and the constraints have been presented in (1)- (11).…”

“…However, the transmission efficiencies are simplified by treating them as constant values, and the model only considered the generator and HV bus side. The OGS problem has been investigated for terrestrial EPS, for instance, the optimal location and sizing of distributed generation sources are formulated in [11] and [12] to minimize the network power losses and better voltage regulation within the frame work of system security constraints in a redial distribution system. These studies contain load flow analysis in their model and they both focus on AC terrestrial grids, while the OGS problem in MEA proposed in this paper should consider different constraints and modelling methodologies.…”

The development of future More Electric Aircraft (MEA) requires exploitation of lightweighted on-board Electrical Power System (EPS) architectural design and energy saving power management strategies. Seeking for the optimal solutions in these key aspects, two vital prerequisites should be ensured for the entire flight stages with load requirements changesone is the optimal power allocation (OPA) aiming to route the power in the system with less transmission losses, and the other one is the optimal generator sizing (OGS) targeting on minimising the required overload capabilities for a lighter generator. Despite different objectives, these two optimisation problems should both meet the load requirements and system operation constraints, including the power balancing and limitations, contactor switching logic, the transmission losses of cables, and the nonlinear converter efficiencies. In this paper, we first propose a formulation method based on the optimal power flow (OPF) model to constitute the system constraints for both optimisation problem, and combining with specific objectives and constraints, the problems of OPA and OGS can be mathematically modelled. By linearizing the nonlinear transmission efficiencies with piecewise functions, the proposed models can be solved using the mixed-integer linear programming (MILP) in CPLEX solver.

“…Flexible modes of operation and use of storage devices in a Microgrid add complexity in its integration with RDS [8][9][10]. Many algorithms are proposed for sizing of components of a Microgrid [11][12][13]. The problem of sizing of sources in islanded Microgrid can be formulated as a minimization problem with the objective to reduce capital, operational and maintenance cost [14][15][16].…”

<p>The performance of Radial Distribution System (RDS) is enhanced by maintaining the appropriate Penetration Ratio (PR) of Distributed generation. However, it has been observed that Penetration Ratio cannot be useful to analyze the impact of a Microgrid on performance of RDS. Hence a new index ‘Relief Factor’ (RF) is defined in this paper and the impact of Microgrid at different RF is studied. This paper presents an approach to compute daily energy losses variation when Microgrids of varying RF are connected to RDS having different maximum demands. A methodology has been proposed for finding optimal RF and location of Microgrid. In addition, the impact of maximum demand of RDS on optimum RF is analyzed. This paper gives the novel concept of assessing the RDS for integration of Microgrid based on maximum demand of RDS as well as Microgrid and sizing of Microgrid based on optimum Relief Factor.</p>
