Stamati, T.E. (author)
A sustainable microgrid for supplying power to electric vehicles (EVs) is investigated in this thesis. The energy produced by the microgrid would be directly transferred to the electric vehicles via on-road charging systems. The proposed sustainable microgrid is located on the roadside and consists of wind turbines, solar panels and a stationary...

The Dutch electricity system is changing and subject to multiple developments. Important developments are the increasing share of distributed energy resources (DER?s) such as solar panels and the increasing use of electronics like computers and televisions. While DER?s produce DC (Direct Current) power, electronics consume DC power. Nevertheless...

Electrical smart microgrids equipped with small-scale renewable-energy generation systems are emerging progressively as an alternative or an enhancement to the central electrical grid: due to the intermittent nature of the renewable energy sources, appropriate algorithms are required to integrate these two typologies of grids and, in particular,...

The traditional ac power system is challenged by the increased amount of distributed energy resources. Enormous changes and investments are necessary in order to achieve an ac smart grid capable of coping with the challenges introduced. In dc, solutions seem to be more straightforward since most of the distributed energy sources and most of the...

DC microgrids can connect directly dc renewable energy sources with increasing amount of dc loads. In this paper it is looked for possible architectures for integrating PV panels into dc microgrids, by means of microconverter strings. Three topologies are considered, featuring only buck microconverters and only boost microconverters, since they...

Advancements in power electronics has sparked the adaptability of dc systems in varied application fields. The phenomenon of electric arcing in such dc systems, arising due to the absence of zero crossing of current during normal operation, has impeded the widespread proliferation of dc-based technologies in the market. Considering the...

In order to cope with various supplies and loads in an autonomous microgrid, a system of sensors and a control unit was developed. The goals of this system are to cope efficiently in the event of an energy supply shortage, and to prevent such events as much as possible. To achieve these goals, the aim was to manage energy in the system as...

Recently, the idea of using fuel cell vehicles as the future way of producing electricity has emerged. A fuel cell car has all the necessary devices on board to convert the chemical energy of hydrogen into electricity. This paper considers a scenario where a parking lot for fuel cell cars acts as a virtual power plant. In order to describe the...

Integration of renewable energy sources in microgrids can be achieved via demand response programs, which change the electric usage in response to changes in the availability and price of electricity over time. This paper presents a novel control algorithm for joint demand response management and thermal comfort optimization in microgrids...

Microgrids equipped with small-scale renewable-energy generation systems and energy storage units offer challenging opportunity from a control point of view. In fact, in order to improve resilience and enable islanded mode, micro-grid energy management systems must dynamically manage controllable loads by considering not only matching energy...

Today 19% of the global population has no access to electricity. Most of these people live in rural areas. These 1,4 billion people would benefit from electricity access for five reasons: their health, education, local economy, sense of safety and communication will benefit. This thesis focuses on off-grid microgrids, with no extension to a main...

In this thesis work we solve the problem of optimal placement and sizing of distributed generation by using an original Fuzzy Adaptive Particle Swarm Optimization algorithm and a Mixed Integer Linear Programming formulation of the problem. The goal of integrating Fuzzy Logic in Particle Swarm Optimization is to be able to overcome some of the...

The inertial response plays a vital role in electrical networks to reduce the rate of change of frequency (RoCoF) following a contingency event. If the inertia has a low or zero value due to a lack of synchronous generators, then the electrical network might experience large undesirable frequency deviations. To overcome this problem, in previous...

The traditional power system has been undergoing fundamental changes during the latest years. The developments in the field of renewable energy sources, as well as in the power electronics industry, acted as drivers aiding the establishment of micro-grids. Nowadays, power production is becoming more and more decentralized, therefore loads and...

The thesis proposes a controller that enables microgrids to have a modular structure, to be flexible in terms of linked energy consumers and resources, and to offer the possibility of prioritized demand side management, while avoiding the need of employing a dedicated communication network. For this, the control strategy applies droop control,...

This paper provides an empirical study on series arc behavior in low voltage dc microgrids. The response of an R-L-C dc microgrid abstraction towards series arcs is studied experimentally for varying grid inductance, dc voltages, load capacitances and load currents. In order to account for the stochastic nature of arcs, experiments are...

Microgrids are suitable electrical solutions for providing energy in rural zones. However, it is challenging to propose in advance a good design of the microgrid because the electrical load is difficult to estimate due to its highly dependence of the residential consumption. In this paper, a novel estimation methodology for the residential load...
