In this paper, an intelligent control strategy based on combination of the “flatness based control technique” and the “perturbation and observation (P&O) MPPT algorithm” is developed and investigated to control a hybrid electric energy source (HEPS). This EHPS is composed of a fuel cell system (FC) and a solar panel (SP), as the main source and a supercapacitor bank (SC), as the auxiliary sourc...

in this paper, an efficient and comprehensive hybrid intelligent technique for the optimal placement of phasor measurement units (pmus) is proposed to minimize the number of pmu installation subjected to full network observability. three main purposes of pmus output synchronous measurements are monitoring, control, and protection of power system. we have combined binary imperialistic competitio...

In this study, effect of energy price on the development of a biomass gasification-solid oxide fuel cell-gas turbine hybrid power plant has been considered. Although, these hybrid systems have been studied based on sustainable approaches, economic aspects, specifically conventional energy prices, which are the principal bottleneck for the development of these new power generators, have attracte...

This paper presents an autonomous hybrid generation system consisting of wind turbine generators (WTG), a diesel engine generator (DEG), fuel cell (FC), a battery energy storage system (BESS) and an aqua electrolyzer (AE). The generated hydrogen by an aqua electrolyzer is used as fuel for a fuel cell. The power system frequency deviates for the sudden changes in load and generation. The output ...

Nowadays, the power system utility has started to consider the green power technology in order for the world to have a healthier environment. A small-scale hybridized solar PV-AC grid (HSPVACG) power system is proposed to be developed to operate with AC grid. This system consists of a photovoltaic array installed on the rooftop. Moreover the roof is flat, which implies that system can be placed...

Analysis of cascading outages in power systems is important for understanding why large blackouts emerge and how to prevent them. Cascading outages are complex dynamics of power systems, and one cause of them is the interaction between swing dynamics of synchronous machines and protection operation of relays and circuit breakers. This paper uses hybrid dynamical systems as a mathematical model ...
