Load emulation is the technique by which, different types of load characteristics can be realized without using the actual load modules. This is very useful for testing of power supply equipment under various load conditions. Further the technique of load emulation can be applied for micro grid design and power flow studies under various load conditions. A battery charger based regenerative load emulation...
This paper deals with the analysis, design and control of a proposed standalone hybrid renewable energy conversion system based on solar and wind energy sources employing a full bridge dc-dc converter and a Permanent Magnet Brush-Less DC (PMBLDC) generator. The proposed MPPT (Maximum Power Point Tracking) controllers of solar-PV (Photo-Voltaic) array and WECS (Wind Energy Conversion System) are operating...
This paper deals with the design, modeling and control of a variable speed Wind Energy Conversion System (WECS) consisting of a permanent magnet brushless DC (PMBLDC) generator, a rectifier, a push-pull converter and a voltage source inverter (VSI) and the maximum power point tracking (MPPT) controller. The proposed mechanical sensorless MPPT controller uses output voltage and current of the rectifier...
This paper deals with the design and modeling of a small scale stand-alone wind energy conversion system (WECS) using a maximum power point tracking (MPPT) controller and permanent magnet brushless dc (PMBLDC) generator. The WECS consists of a wind turbine, PMBLDC generator, MPPT controller, isolated half bridge dc-dc converter, battery, voltage source inverter (VSI) and output filter. The fuzzy logic...
This paper presents a design and modeling of a sensorless maximum power point tracking (MPPT) controller using a permanent magnet brush-less DC (PMBLDC) generator for a wind energy conversion system (WECS). A low power WECS is designed with an isolated flyback dc-dc converter, a battery and a voltage source inverter (VSI). The sensor-less MPPT control is based on the power-speed curve of a wind turbine...
This paper presents the design procedure and performance of a solar-PV (photovoltaic) energy generating system using an isolated zeta converter for meeting an energy demand of rural households. The solar-PV generating system consists of solar panels, a zeta dc-dc converter, a MPPT (maximum power point tracking) controller, energy storage system, VSI (voltage source inverter) and a filter. A feedback...
This paper presents the design and performance of a low power stand-alone solar photovoltaic (PV) energy generating system. The system is designed considering solar-PV panels of 750W to feed an average load demand of 250W for a rural household. The system includes series-parallel combination of solar panels, MPPT (maximum power point tracking) controller, a dc-dc converter, an energy storage system...
This paper deals with the design, control and modeling of an isolated solar-PV (Photo-Voltaic) energy generating system. The proposed system is designed for supplying an average consumer load of 1.5 kW. A constant voltage method is applied to the PV array for MPPT (Maximum Power Point Tracking). A push-pull boost dc-dc converter is fed from the PV array for charging the battery. A VSI (Voltage Source...
