With the increasing of energy demand for air conditioning purpose in Algeria, absorption solar cooling systems represents a very good alternative for clean cooling production where over-consumption of electricity occurs. In this paper, a modeling and simulation of an absorption solar cooling machine under Algerian climate is presented. This study was based on a single stage absorption cooling machine...
In this paper, we present a system used a Permanent Magnet Synchronous Generator (PMSG) applied to wind energy, to generate electricity and inject it into home network. The objective is to perform modeling and nonlinear control system, and then the objective of the control is: enforcing power factor correction (PFC) with respect to the power grid. First part, we present the mathematical model of the...
In this paper, we present a simulation of the predictive control named Linear Quadratic Gaussian (LQG) in order to control the temperature under greenhouse. This controller permits to estimate the gain of Kalman filter by resolving the Riccati equation. For that, we are using Matlab software to develop the state equation to be implemented in LabVIEW software.
The main purpose of this paper is to present a 1-D modeling with simple equations to describe the behavior in the oscillating water column device (OWC) used for wave energy conversion. The free water surface inside the chamber is considered as a piston water mass moving up and down due to the successive incident waves from the sea. Analyses are focused on the temporal variation of wave height inside...
The exponential increase of electric energy demand, in parallel with the forthcoming exploration of Distributed Energy Resources (DER), as Renewable Energy Resources (RES), makes the future electric network more and more complex, therefore it is required the implementation of active distribution networks, with rapid control decisions counter to the passive or conventional power network. This paper...
The objective of this article is to compare two topologies of converters Boost DC-DC, classical and interlaced, in terms of the values of the amplitudes of currents their output voltage and undulations, size of the components of the converters and delivered power. Our work presents a technical approach for the improvement and the optimization of the adaptation's performances of power of a photovoltaic...
Mathematical modeling of photovoltaic (PV) modules is essential for any performance optimization operation or diagnostic of the photovoltaic generator under changing environmental conditions. The limited data available are provided by commercial manufacturing datasheets. The accurately estimating of these parameters remains a challenge for researchers. There is great diversity in the models and the...
