This paper presents a multipurpose three-phase double-stage grid interfaced photovoltaic (GPV) system using an adaptive nonlinear control strategy. Along with a peak power extraction from a photovoltaic array, the proposed system is capable of harmonics currents elimination, reactive power compensation, grid currents balancing, and adaptive dc-link voltage control. The fundamental and harmonics information...
In this paper, control and operation of a microgrid having inverter based solar photovoltaic (PV) and diesel engine is presented. The microgrid is designed to meet rural applications. In the proposed microgrid, a water pumping system is considered as a dump load for ensuring economic operation of microgrid. Three scenarios i.e fully loaded, partially loaded and lightly loaded are considered to evaluate...
In real time field conditions, situation arises when sudden and a large change in insolation level occurs. Such frequent fluctuations in irradiation level, affects adversely the performance of Photovoltaic (PV) based water pumping system. Sudden large fall in insolation leads to generation of PV power which is insufficient for operation of motor-pump system and such frequent variations in insolation...
In this paper an modified MISO DC-DC converter based Photovoltaic (PV) water pumping system is designed for population living in remote areas to fulfill their water pumping requirement for various applications like drinking water, water for irrigation and daily needs etc. With the objective of improvement in performance and efficiency of PV based water pumping system and thus to justify its installation...
Partial shading and/or mismatching phenomena in Photovoltaic (PV) based system cause reduced extraction of PV power and thus adversely impact the performance of PV based system; especially in case of stand-alone PV systems. In this paper four different configurations namely single stage PV system, centralized DC-DC converter based PV system, PV panel level Distributed maximum power point tracking...
In this paper an isolated Photovoltaic (PV) system is proposed for rural applications like water pumping for irrigation, daily needs and drinking water etc. Series connected PV modules (SCPVM) provides a cost effective solution due to reduced conductor cross-sectional area and relatively low converter gain. With the objective of improvement in performance and efficiency of isolated SCPVM based PV...
