Utility companies have been seeking methods to operate electricity distribution infrastructures efficiently. Smart grid applications provide opportunities to network operators to collect data from consumers. Therefore operators could track power consumption based on historical and immediate data. Thanks to remotely collecting data, operators take necessary action to manage changes in consumption rate...
Decarbonisation policies adopted worldwide are leading to an increasing deployment of renewable energy sources. In Europe, the growing number of offshore wind farm projects calls for scrutinising merits and opportunities of their interconnection via multi-terminal links rather than conventional point-to-point connections. The semiconductor components used in the converters and the resistance of power...
By applying new technologies of energy and DC distribution technology, the smart-grid based digital load device is increased. Due to the power conversion technology, the power consumption is minimized, maximize the utilization of self-development self-energy power consumption. Derive optimum efficiency power structure, and at the same time, the existing AC system with high quality bi-directional AC-DC...
Renewable energy sources have been an attraction for both researchers and scientists recently. In this study, a survey focused on renewable energy sources in Turkey has been presented. The survey has been conducted by researchers working in different scientific disciplines registered to Scientific and Technological Research Council of Turkey. The questionnaires have been prepared in order to explore...
One of the two hydro turbine-generator sets in small hydropower plant has become inoperable due to generator stator winding failure. Considering the age of the plant, together with generator repairs, more comprehensive plant refurbishment options have been analysed. The optimal solution is chosen, one that provides improved reliability, increased electricity production with best financial and economic...
This paper explores important characteristics of multiple-input converters (MIC) serving as a power electronic interface for renewable energy applications. Advantages of MICs are explained through an example with a photovoltaic (PV) system. Feasible MIC topologies for renewable energy applications are discussed and classified into four different MIC families. According to their different configurations,...
Nowadays, there are several difficulties are met in the selection of appropriate conditions, place of use, and purpose of photovoltaic (PV) systems. The reason is that electrical power output of PV system shows a non-linear variation, unlike other applications, depending on the internal resistance of electrical devices (loads) as well as radiation intensity and environmental temperature. Therefore,...
The extraction of energy from ocean waves has been investigated in Europe since the 1970s. Several devices have been proposed and a few of them have been built full scale and deployed to the ocean. Actually there is not a kind of device that is accepted as the most suitable to exploit wave power.
The effectiveness of two patterns for operating a self-sufficient (i.e., smart) microgrid was investigated. One pattern minimizes connection time to the utility power grid, and the other minimizes the peak load drawn from the utility power grid and maximizes battery life. Field testing of a demonstration system showed that it can switch between modes (island, charge, and backup) and continue to supply...
