A New Control Method for Single-Phase Grid-Connected Inverter Using Instantaneous Power Theory
Because of installation for local consumers and since it is free of all contaminations, connecting photovoltaic cells to the grid via single-phase inverter is significantly on the rise. In this paper, a new simple current control is proposed for a single-phase grid-connected voltage source inverter. Using the PQ theory and modelling a single-phase system as an unbalanced three-phase system, a m...
متن کاملComparative Analysis of Types of Shunt Hybrid Power Filter Using Instantaneous Power Theory
The use of nonlinear load led to the injection of harmonics into the power system. In this paper, the performance of two topologies of shunt hybrid power filters for compensating voltage and current harmonics in the distributed power generation (DPG) system has been compared. The control algorithm used in this paper is the p-q theory for the harmonics compensation. The performance of these topo...
متن کاملA generalised instantaneous non-active power theory for STATCOM
A generalised instantaneous non-active power theory is presented. Comprehensive definitions of instantaneous active and non-active currents, as well as instantaneous, average and apparent powers, are proposed. These definitions have flexible forms that are applicable to different power systems, such as single-phase or multi-phase, periodic or non-periodic and balanced or unbalanced systems. By ...
متن کاملA New Strategy for Simultaneous Compensation of Instantaneous Reactive Power and Harmonics of Non-Linear Loads (RESEARCH NOTE)
This paper presents a new control method for simultaneous compensation of instantaneous reactive power and current harmonics by parallel active filters (PAFs). Reference compensating currents of PAF are calculated using the subtraction of instantaneous power from its average value. In this way, it is possible omitting high/low pass filter(s) from the control circuit of PAF, which usually result...
متن کاملExperimental Characterization of Hybrid Power Systems Under Pulse Current Loads
The electrochemical performance characteristics of a prismatic lithium-ion battery, ultracapacitors, and hybrid combinations at ambient temperature are considered. The effects of pulse current, duty cycle and hybrid combinations are studied. Current pulsing was shown to improved the total energy discharged from the lithium-ion battery and battery / capacitor hybrid combinations over that of a c...
