A home solar power system for micro electric vehicles (EVs) is one of the important technologies to realize a sustainable energy society. The aim of this paper is a demonstration of a high performance digital control phase-shifted full-bridge converter connected between solar panels and the dc-bus line. Since the voltage in a home storage battery and EV battery is around 72V in some products, the...
This paper presents the influence of non-conventional sources like central station solar photovoltaic model and wind plant model in multi-machine power system for transient stability. Modified four-generator system is studied by replacing one of the conventional synchronous generators with solar photovoltaic and wind generator model. The performance is compared with the classical four-generator system...
The expanding installation of photovoltaic (PV) resources into power systems continue to grow which affects both structural and dynamics of power systems. The effects of large-scale grid-connected PV on the stability of power systems becomes a serious concern, because of the different dynamic behaviour of the power system with a considered portion of inertialess of the P-V based systems. This paper...
When alternative power sources are connected to the utility grid the core characteristics of the system are changed. This fact is especially true for intermittent, volatile power sources such as photovoltaic (PV) systems. In recent years, PV power systems have become increasingly cost competitive leading to greater penetrations of both large and small scale PV systems. The large scale integration...
This paper studies the operation of a microgrid under various scenarios with a focus on the effect of communication delays. The test microgrid is the CIGRE-IEEE low-voltage system, and a variety of loads are modeled in the system, including a nonlinear load, an impulse load, a battery, a highly capacitive load, and a highly inductive load. The simulation studies cover three scenarios: 1) a system...
As the conventional sources of energy (example. oil, gas, coal) are decreasing day by day in the world, renewable energy is going to be the leading energy source in the future. Among all the sources of renewable energy solar PV generation is the potential source for generating power. Penetration of significant amount of solar photovoltaic generation is a challenge for power system stability. Solar...
This paper is devoted to study the impact of the PV systems on electrical grids. This paper investigate the stability response of a Single Machine Infinite Bus (SMIB) system with a PV installation at the middle of the transmission. A mathematical model of a single-machine infinite-bus power system integrated with a PV power generation plant is established. Both the non-linear and linear dynamic model...
Simultaneous dropout of a large amount of distributed generators caused by a fault in a power line with voltage drop and/or phase change may worsen power stability of a trunk power system. A reduced model of distributed generators in secondary systems considering partial dropout is proposed for the stability analyses. To verify the reduced model, a detailed model and the proposed reduced model are...
