“…During the analysis by the AVR, a system transient does not hit any limit; the voltage transducer time constant T R is ignored by assuming very fast voltage processing. The transient gain reduction (TGR) bloc allows the controlled rectifier dead time compensation and reinforces the closed loop stability; the use of TGR may not be critical for AVR stability if the rectifier is fast enough; equations (‐) governing the AVR transients are given below:

p ((), _{Δ v_{2}}) = - \frac{1}{T_{s}} normalΔ v_{2} - \frac{T_{s} - T_{c}}{T_{s}^{2}} normalΔ v_{t},

p ((), _{Δ E_{f}}) = \frac{K_{A}}{T_{A}} normalΔ v_{2} - \frac{1}{T_{A}} normalΔ E_{f} - \frac{K_{A} T_{c}}{T_{A} T_{B}} normalΔ v_{t},

normalΔ v_{1} = - normalΔ v_{2} - \frac{T_{c}}{T_{B}} normalΔ v_{t},

normalΔ E_{f} = \frac{X_{italicmd}}{r_{f}} normalΔ v_{f},

p ([], \begin{matrix} {Δv}_{2} \\ {normalΔ E}_{f} \\ {normalΔ ψ}_{t 1} \\ {normalΔ ψ}_{t 2} \end{matrix}) = A_{2} ((), θ_{ε}) ([], \begin{matrix} {Δv}_{2} \\ {normalΔ E}_{f} \\ {normalΔ ψ}_{t 1} \\ {normalΔ ψ}_{t 2} \end{matrix})

Summary Algeria is in a region with an enormous potential of solar energy for power generation. However, photovoltaic (PV) power plants have not yet been developed sufficiently in the country, and its applications such as PV pumping, solar distillation, and solar heating. The main problem is the high maintenance, operating costs, fossil‐fuel transportation, and CO2 emission of Bordj Badji Mokhtar's (BBM's) diesel power plant that exhibits a noteworthy issue in south Algeria. This paper presents the results of a theoretical and experimental study for PV/diesel hybrid energy system (HES) considering the load demand profile and the solar radiation in isolated area of south Algeria. Suggested hybridization based on a renewable energy with a view to an improved environment is promising. Study results show the performance of PV/diesel system based on solar radiation. The experiment load curve in this typical area may conduct the diesel generator to operate at 60% to 70% of its nominal power with less fuel consumption, and it has been verified during this study that the implementation of a PV/diesel hybrid system is efficient for higher load and higher solar radiation. Results and discussions are encouraging considering less emission of greenhouse gases and less storage of fuel, which drives the government to draw a political arrangement for the improvement of cleaner forms of electricity generation.

A state-space representation of a Synchronous generator is established and used to analyze the transient behavior of a Synchronous Generator. The machine is a 2 pole, 150 MVA, 120 MW, 13.8 kV, 50 Hz generator connected to an infinite bus through a transformer and a transmission line. The state-space representation is based on a two-axis equivalentcircuit model of the generator and includes the swing equation and the voltage regulator. The two-axis representation of the infinite bus voltage is chosen as reference. A three phase short circuit is simulated at the transformer terminals. Graphic results are analyzed and compared with actual measurements and with those obtained from a finite element model of the generator. The results give insight into the electromagnetic phenomena and the state-space representation provides a platform for the analysis of control schemes to improve the stability of the generator.

The singular perturbations theory for a class of nonlinear systems with a bond graph approach is proposed. Also, the state equation of a class of nonlinear systems with singular perturbations modelled by bond graphs is described. Hence, a new junction structure to get the quasi-steady state model for a class of nonlinear systems is proposed. This junction structure has the fast storage elements in derivative causality and the slow storage elements in integral causality. The proposed methodology is applied to a synchronous machine.
