Abstract:

The existing power grids that form the basis of the respective electrical power infrastructures for various states and nations around the world, are expected to undergo a period of rapid change in the near future. The key element driving this change is the emergence of the Smartgrid. The Smartgrid paradigm represents a transition towards an intelligent, digitally enhanced, two-way power delivery grid. The aim of the Smartgrid is to promote and enhance the e_cient management and operation of the power generation and delivery facilities, by incorporating advanced communications, information tech

Abstract:

In recent years, power systems are facing with various challenges arising from the increased share of renewable energy systems. Among all sections of power systems, distribution grids are affected the most since the majority of renewable energy sources are connected to distribution grids. As the penetration of Variable Energy Sources increases in electric grids, energy storage systems have become more influential. In this context, this thesis presents a new algorithm for the optimal operation of Battery Energy Storage Systems in distribution grids. The proposed algorithm aims to define the opt

Abstract:

As vehicles become electrified and more intelligent in terms of sensing, actuation and processing; a number of interesting possibilities arise in controlling vehicle dynamics and driving behavior. Over-actuation with inwheel motors, all wheel steering and active camber is one such possibility, and can facilitate control combinations that push boundaries in energy consumption and safety. Optimal control can be used to investigate the best combinations of control inputs to an over-actuated system. In Part 1, a literature study is performed on the state of art in the field of optimal control, hig

Abstract:

The present work is concerned with the plant of the sport palace “Carmine Romanzi”, known also as “Palacus”, of University of Genoa (Italy). The facility consists of a heat pump coupled, on the cold side, with the thermal part of a solar hybrid field. The hot side of the heat pump has been designed to satisfy the space heating and domestic hot water needs of the structure. The photovoltaic production of the solar hybrid field grants the electricity need of the heat pump and any other electric auxiliary within the plant.

Abstract:

To reduce fossil fuel consumption and carbon emission in the building sector, renewable and low carbon energy technologies are integrated in building energy systems to supply all or part of the building energy demand. In this research, an optimal supervisory controller is designed to optimize the operational cost and the CO2 emission of the integrated energy systems. For this purpose, the building energy system is defined and its boundary, components (subsystems), inputs and outputs are identified. Then a mathematical model of the components is obtained.

Abstract:

In line with The Paris Agreement, the world is now changing towards more sustainable options for all sorts of energy development. The solar energy sector is growing rapidly as a result of this. One area that holds great potential in changing many of the worlds heating processes, is concentrating solar power (CSP). The basic principle of CSP is to reflect incoming sunlight and concen- trate it to heat a fluid. To do so, it is crucial to find a reflector material that shows both good optical performance initially as well as over time to produce heat in the most efficient way possible and compete
