چکیده
Proton exchange membrane fuel cell (PEMFCS) and electrolyser (PEMELS) systems, together with a hydrogen storage tank (HST), are suitable to be integrated renewable microgrids cover intermittency fully exploit the excess of electrical energy. Such an integration perfectly fits telecom tower power supply needs, both in off-grid grid-connected sites. In this framework, model-based tool enabling optimal sizing proper year-through energy management above applications is proposed. Respectively, islanded optimisation performed considering two economic indices, i.e., simple payback (SPB) levelised cost (LCOE), strategies management, charge sustaining depleting, also accounting for impact grid extension distance. On other hand, connection addressed through dynamic programming method, while downsizing PEMELS HST sizes improve techno-economic effectiveness, thanks contribution towards renewables curtailment issues mitigation. For introduced strategies, reduction more than 70% nominal 90% size, which will turn lead SPB LCOE being reduced by 80% 60% comparison case, respectively, achieved. Furthermore, depleting strategy, relying on possible purchase, interestingly provides 9% 7% lower one.

Design and Simulation of a New DC Power Supply Based on Dual Bridge Matrix Converter
A conventional high power DC power supply systems consist of a three-phase diode rectifier followed by a high frequency converter to supply loads at regulated DC voltage. These rectifiers draw significant harmonic currents from the utility, resulting in poor input power factor. In this paper, a DC power supply based on dual-bridge matrix converter (DBMC) with reduced number of switches is p...
متن کاملA new approach based on state conversion to stability analysis and control design of switched nonlinear cascade systems
In this paper, the problems of control and stabilization of switched nonlinear cascade systems is investigated. The so called simultaneous domination limitation (SDL) is introduced in previous works to assure the existence of a common quadratic Lyapunov function (CQLF) for switched nonlinear cascade systems. According to this idea, if all subsystems of a switched system satisfy the SDL, a CQLF ...

متن کاملModelling and Simulation of Water Supply Systems for Feedback Control
Operation principles of water supply systems are considered and the mathematical expressions for the system major components such as pipes, reservoirs and pumps are represented. Behaviour of thesystem is investigated by slow movement of fluid flow around steady-state operating point. Head losses changing nonlinearly with water flowrates in pipes are represented by the Darcy-Weisbach and the Haz...
