A control strategy of hybrid system “diesel-photovoltaic-battery” for stand-alone applications

Abstract

this paper describes a control strategy of a dieselsolar-battery hybrid system for standalone applications. the PV generator and batteries are primary sources of energy in the system; diesel generator is interconnected to the AC bus, when approached it can supply power load and charges batteries simultaneously ; as it can supply part of power load in parallel with the PV generator and batteries. In this context, the DC / AC converter that connects the DC bus to AC bus is synchronized with the diesel generator; it can function as either an inverter or as a rectifier, according to the load power.In order to validate the performance of the control strategy, some simulations using MATLAB/SIMULINK, will be shown firstly, and secondly, experimental tests will be performed.

Performance Tuning for Power Electronic Interfaces Under VSG Control

“…Two classical models, the 'synchronverter' and Ise's, focus on the loss of inertia in conventional VSI droop control, and the emulation of the properties of the inertia and the speed-governor is implemented [9,11,13]. Experiment-based studies can be found in [14,15] for stand-alone applications. In [12], the equivalence between the VSG and the frequency-droop algorithms are demonstrated.…”
