Regulation of Current/Voltage Characteristics in Photovoltaic Pumping Systems
نویسندگان
چکیده
A PV pumping system using induction machine is thoroughly investigated in this work. The power structure is constituted of multiple parallel DC/DC step-up converters directly connected to the inverter. Each DC/DC converter is used as a DC current transformer. The input characteristic of the inverter is enforced by means of an appropriate regulation, in order to avoid problematic dynamic resistance. The system is simulated under Matlab / Simulink and it has been shown that the proposed regulation scheme is unconditionally stable.

An Online Free Penetration Multi-Stage Fuse Saving Protection Scheme in Distribution Systems with Photovoltaic Sources
In this paper, a multi-stage protective scheme is proposed to maintain the fuse and reclosers coordination. The proposed method operates online and proportional to the photovoltaic sources penetration rate. In the first step, a non-standard Current - Time - Voltage curve is used for fuse saving. If the new calculated TDS from the first stage is not implementable to the reclosers, the second sta...
