Decarbonization is an ongoing issue in the shipping industry, and electric propulsion systems are being proposed as alternative solutions to satisfy this requirement. To answer fundamental questions of “Are green solution?” “Can DC distribution contribute decarbonization shipping?”, paper analyzed system electrical characteristics, economic feasibility, environmental evaluation for a full-scale...

This paper presents the design of a low cost voltage controller of a single phase Self-Excited Induction Generator (SEIG). The control scheme is based on the measurement of users load voltage and controlling the dump load power using an Analogue Input Power Controller (AIPC). The controller output varies from 2 -10V and it controls the output AC power going to a resistive dump load. A PI type c...

optimal reactive power dispatch (orpd) is a multi-variable problem with nonlinear constraints and continuous/discrete decision variables. due to the stochastic behavior of loads, the orpd requires a probabilistic mathematical model. in this paper, monte carlo simulation (mcs) is used for modeling of load uncertainties in the orpd problem. the problem is formulated as a nonlinear constrained mul...

This paper presents an Interior Pont Method (IPM) and variant of Particle Swarm Optimization (CFAPSO) based hybrid method to solve optimal power flow in power system incorporating Flexible AC Transmission Systems (FACTS) such as Thyristor Controlled Phase Shifter (TCPS) for minimization of multiple objectives. The proposed IPM-CFAPSO algorithm identifies the optimal values of generator active-p...

In this paper, the performance analysis of wind turbine as a distributed generation unit is presented. In this study a model of wind power is driven by an induction machine. Wind power that is distributed generation is capable of supplying power to ac power distribution network. Wind power generation system is modeled and simulated using Matlab Simulink software such that it can be suitable for...

We show that Thompson’s group F does not satisfy Cannon’s almost convexity condition AC(n) for any integer n in the standard finite two generator presentation. To accomplish this, we construct a family of pairs of elements at distance n from the identity and distance 2 from each other, which are not connected by a path lying inside the n-ball of length less than k for increasingly large k. Our ...

In this paper a novel optimal control strategy for energy management of an off-grid hybrid Stirling engine/Supercapacitor power plant is presented based on preliminary results proposed in [1]. An implementation of the control strategy is performed on a real time target that drives a dedicated testbed with a DC machine reproducing the behaviour of the thermodynamic Stirling Engine. The DC machin...

The paper investigates the small-signal stability of a 270V DC power system for a more electric aircraft, which employs switched reluctance generator technology and multiple distributed power electronic converters for flight control surface actuation, environmental control, and numerous DC and AC loads. Non-linear state space models for the complete system have been established and the eigenval...

In this paper, we present the concept of transmitting power without using wires i.e., transmitting power as microwaves from one place to another is in order to reduce the transmission and distribution losses. A wireless power transmission using microwave is a system which contains satellite based solar power system (SPS), microwave generator, microwave transmitter (magnetron) and microwave rece...

The design of a fully superconducting wind power generator is influenced by several factors. Among them, low number pole pairs desirable to achieve AC losses in the stator winding, which greatly influences cooling system and, consecutively, efficiency entire plant. However, it has been identified that tends increase its output voltage, turn creates challenging conditions for necessary electroni...
