Abstract:

This thesis aims to research the effects of multiple ascending levels of photovoltaic (PV) power penetration on a prototype diesel generator powered network that has a PV power system integrated into it. First the effects of this additional photovoltaic penetration were documented then some ways to mitigate the effects of solar intermittency were investigated. This project relates to the Power and Water Corporation’s (PWC) proposed roll out of 10 megawatt of solar throughout more than 30 of the remote communities they service in the Northern Territory.

Abstract:

<p> Distribution systems are designed to operate in radial mode (the simplest system topology) without any generation on the system, unidirectional power flow from the distribution substation to the customers via main feeder(s) and its(their) laterals within a specified range of operating points. The rapid growth of PV module installations on the distribution systems could not only offset the load but also cause a significant impact on the flow of power (active and reactive), voltage level, and fault currents, therefore; concerns about their potential impacts on the stability and operation of

Abstract:

The aim of this work is to research the issue of optimal sizing and location of photovoltaic distributed generation (PVDG) units on radial distribution feeders, and develop new procedures by which the optimal location may be determined. The procedures consider the concept that the PVDG production varies independently from changes in feeder load demand. Based on that, the developed procedures deal with two performance curves; the feeder daily load curve driven by the consumer load demand, and the PVDG daily production curve driven by the solar irradiance. Due to the mismatch in the profile of t

Abstract:

The proposed hybrid system generates AC power by combining solar and wind energy converted by a doubly-fed induction generator (DFIG). The DFIG, driven by a wind turbine, needs rotor excitation so the stator can supply a load or the grid. In a variable-speed wind energy system, the stator voltage and its frequency vary with wind speed, and in order to keep them constant, variable-voltage and variable-frequency rotor excitation is to be provided. A power conversion unit supplies the rotor, drawing power either from AC mains or from a PV panel depending on their availability. It consists of a mu

A paramount technical drawback of photovoltaic (PV) and wind power systems is the intermittency of energy production, which results in problems of stability of the electricity grid and power quality issues [1] [2] [3]. The effects of the separate installation of PV or wind power systems are well-known in literature [4] [5] [6]. In different countries, such as Denmark for wind, renewables have become the main sources of power: non-programmable RES share is currently around 50% of the national electric consumption.

The wide diffusion of distributed energy resources (DERs) has led to a scenario where the penetration of renewables is very high and can significantly affect the grid stability. The increasing complexity of these systems requires a suitable stability approach: the impedance-based analysis has one of its main advantages in the possibility to characterize the components separately, e.g. source and load, and to estimate the stability at a certain interface applying the Nyquist criterion to the impedance ratio.

Abstract:

La perte de puissance d'un générateur photovoltaïque (GPV) est sans conteste due à l'apparition d'un certain nombre d'anomalies liées à la fabrication, à la production ou à l'environnement, engendrant des défaillances dans son bon fonctionnement. A partir d'un modèle réaliste, assez proche du fonctionnement réel et capable de prendre en compte l'effet d'avalanche d'une jonction PN transmise à l'ensemble du GPV, nous avons montré à suffisance, la perte de performances d'un générateur PV et la nécessité d'avoir une méthode de diagnostic pour l'aide à la maintenance afin de ne pas subir les effet

In the recent times distributed generations or renewable energies are very much needed for daily usage as the natural resources are on the verge of extinction. These renewable energy sources are a very good solution for the global energy problem. The usage of renewable energy, according to the statistics is around 17% all over the world, from which only 0.06% constitute of solar PV power. These statistics show that we are lagging behind from extracting the solar power. There are various factors that can be hold accountable for this viz. very costly equipment, lack of knowledge and even we do n

Nowadays, popularity of renewable energy has made synchronization one of the necessary technologies in the grid interface. In a single-phase PV inverter, stationary and synchronous coordinate transformation has allowed the grid voltage, frequency and phase to be tracked and synchronized. The phase-locked-loop (PLL) model is first built in the Alternative Transients Program (ATP) to observe if overvoltage happens at the point of common coupling (PCC)

Abstract:

In these uncertain times having a clean, secure and definable energy supply will be a key ingredient necessary to provide a platform to underpin and stabilise our financial and economic systems while removing one of the greatest causes of political conflict. The solar energy resource is widespread and can provide more than a thousand fold for our energy needs for the foreseeable future. To effectively harness this energy a number of challenges must be met to overcome shortcomings and inertia including aspects of a technical, social and political nature.
