Output power in a hybrid power system is constant while the input power with variable characteristics that is generated by different sources. Using Hybrid Electrical Energy Storage (HEES) systems, is growing rapidly since there is an obvious need for clean energy. This paper introduces different parts of a HEES system and then proposes HEES systems which employ battery, ultracapacitor and f...

This paper presents a hierarchical control strategy for heat and electric power control of a building integrating hybrid renewable power sources including photovoltaic, fuel cell and battery energy storage with Plug-in Electric Vehicles (PEV) in smart distribution systems. Because of the controllability of fuel cell power, this power sources plays the main role for providing heat and electric p...

Today, the whole world faces a great challenge to overcome the environmental problems related to global energy production. Most of the islands throughout the world depend on fossil fuel importation with respect to energy production. Recent development and research on green energy sources can assure sustainable power supply for the islands. But unpredictable nature and high dependency on weather...

in this paper, the development and optimization of power distribution control strategy (pdcs) have been performed for a hybrid energy storage systems (hess) of a series hybrid electric bus (sheb). a common pdcs is based on the use of ultra-capacitor (uc) pack. a new simple pdcs is developed as a battery based one. for the battery based pdcs, four parameters are introduced for tuning the pdcs pe...

This paper deals with the power quality (PQ) improvement by using a transformer less Hybrid Active Power Filter (HAPF) based on a six switch two leg inverter with battery and solar system through boost converter which increases the reliability of power supply by reducing the Total Harmonic Distortion (THD) and increase the voltage level. The control methods of instantaneous reactive power theor...

The function of our new marine hybrid turbocharger, which has a generator on its rotor shaft, is to supply electric power for consumption onboard a ship and to supercharge the ship’s diesel engine. The generator is driven by the turbocharger shaft, which is rotated by exhaust-gas energy; thus, the generator is an exhaust-heat-recovery device, and energy savings can be expected. A high-speed, hi...

The power quality issues are of great concern now a days. The increasing use of power electronic devices based nonlinear loads deteriorate the quality of power. Power electronic appliances are widely used in industrial, commercial and utility system thus leading to various power quality problems. This leads to harmonics being injected into the distribution system and also reactive power burden....

Abstract: The use of the isolated hybrid power systems is being popular due to the continuous increasing gap between demand and supply of conventional energy sources and intermittent nature of non-conventional energy sources. Normally, the non-conventional energy source such as wind have induction generator to generate electricity but induction generators require reactive power for its operatio...

This study is to identify performance of energy efficiency measures and to match low-carbon and renewable energy (RE) systems supplies to demands in the context of multi-family residential buildings in Korea. An approach to the evaluation of the hybrid energy systems was investigated, including consideration of heat and power demand profiles, energy system combinations, building design options ...
