Flywheels are typically used as storage elements in isolated wind plants, especially those running at almost constant speed, connected to synchronous generators and diesel engines. Nowadays, systems with variable speed are under development, so the amount of available energy in the flywheel is highly increased. In this paper a comparison between an almost constant speed system and variable spee...

The wind energy conversion systems when operate in weak grid or in isolated mode may cause power quality problems due to variation in wind speed and other circuit conditions. To improve the power quality of wind generation system a wind-diesel hybrid system is proposed in this paper. The power quality of the system is improved by controlling the excitation and input power of the synchronous gen...

This study aims to estimate the fuel consumption of marine diesel generators onboard. Objective technical specifications and operational data on ship's power generating plants port calls were collected from an oceangoing oil/chemical tanker used develop mathematical model plant in Python MATLAB environment. The consists alternators, prime movers load distributions ship’s provides information me...

This study investigates the emission of a heavy-duty diesel engine generator fueled with waste cooking oil (WCO)based biodiesel blends (W) and operated at 1.5 and 3.0 kW loads. A brand of pure fossil diesel was adopted as the base fuel, with 20% and 40% WCO-based biodiesel added into the based fuel to form W20 and W40 blends, respectively. The emission characteristics of PM, metals and PAHs wer...

Energy shortage and environmental problems are two dominant subjects. The diesel engine is well-known for its high thermal efficiency but severe emission problems. For the urgent fossil fuel resources, substantial surrogate fuel, dimethyl carbonate (DMC) attracting attention oxygen content. Its application in engines has won increasing focus. However, it difficult to directly with DMC due low c...

This paper presents a comparison of two different adaptive control schemes for improving the performance of a hybrid wind-diesel power system in an islanded microgrid configuration against the baseline controller, IEEE type 1 automatic voltage regulator (AVR). The first scheme uses a model reference adaptive controller (MRAC) with a proportional-integral-derivative (PID) controller tuned by a g...

Water irrigation systems (WISs) are an important factor for agricultural development and food security. However, their energy supply is affected by several problems related to the use of diesel generators, especially in remote areas. This paper describes a new methodology used design cost-effective sustainable solution provide water system with demand 40 kWh/day. A combined side management (SSM...
