Abstract:

DC power distribution has gained popularity in sustainable buildings, renewable energy utilization, transportation electrification and high-efficiency data centers. This dissertation focuses on two aspects of facilitating the application of dc systems: (a) system-level control to improve load sharing, voltage regulation and efficiency; (b) design of a high-efficiency interface converter to connect dc microgrids with the existing low-voltage ac distributions, with a special focus on common-mode (CM) voltage attenuation. Droop control has been used in dc microgrids to share loads among multip

Abstract:

Long term supporting schemes for photovoltaic (PV) system installation have led to accommodating large numbers of PV systems within load pockets in distribution grids. High penetrations of PV systems can cause new technical challenges, such as voltage rise due to reverse power flow during light load and high PV generation conditions. Therefore, new strategies are required to address the associated challenges. Moreover, due to these changes in distribution grids, a different response behavior of the distribution grid on the transmission side can be expected. Hence, a new equivalent model of dis

Abstract:

Renewable energy sources are being widely adopted by more and more countries due to their comparatively low cost, flexibility, and environmental benefits. Grid-forming control is becoming an important technology to address the stability issues resulting from the retirement of conventional synchronous generation. Unlike conventional grid-following inverters, predominantly used today for the connection of wind and solar farms, grid-forming inverters behave much like synchronous machines by providing both inertia and system strength. Against this backdrop, this thesis investigates the problem of

Abstract:

In this research project, a low-cost local voltage compensation strategy is proposed that evenly utilises the capability of the customers’ inverters spreading over a branched suburban utility network. The improved utilisation is based on a straightforward two-element equivalent of the network locally seen by each inverter. The network is simultaneously probed by all inverters, each one tries to identify its two-element perspective. Receiving an appropriate local response is challenged by the interference created by simultaneous probing and demand variation and also inverters’ compensating natu

This thesis focuses on the development of a low power energy harvesting system specifically targeted for wireless sensor nodes (WSN) and wireless body area network (WBAN) applications. The idea for the system is derived from the operation of a micro-grid and therefore is termed as a pico-grid and it is capable of simultaneously delivering power from multiple and multitype energy harvesters to the load at the same time, through the proposed parallel load sharing mechanism achieved by a voltage droop control method.

Abstract:

Driven by technical, economic and environmental benefits for different stakeholders in the power industry, the electric distribution system is currently undergoing a major paradigm shift towards having an increasing portion of its growing demand supplied via distributed generation (DG) units. As the number of DG units increase; microgrids can be defined within the electric distribution system as electric regions with enough generation to meet all or most of its local demand. A microgrid should be able to operate in two modes, grid-connected or islanded. The IEEE standard 1547.4 enumerates a li

Abstract:

A system-on-chip (SoC) with near-threshold supply voltage (NTV) operation has received a significant amount of attention. Its high energy-efficiency supports a number of low-power emerging applications such as wireless sensor networks and Internet-of-Thing edge devices. Integrating various digital, analog, mixed-signal, and power sub-systems, such SoC designs need to employ tens of voltage domains to push the envelope of energy-efficiency, performance, and robustness. A low-drop-out (LDO) regulator is a key building block for creating voltage domains on a chip thanks to its high power density.

With growing environmental concerns and sustainability movements, renewable energy source (RES) penetration is increasing and expected to have a steady growth in the coming years. Power systems have encountered several inherent technical challenges, resulting from either low inertia contribution by the increased RES or the displacement of fossil fuel generation systems within the network. The decreased system inertia and the decline in power reserve capacity are affecting the dynamic and transient stability performance of the power system adversely and this adverse impact will continue to incr
