As an introduction to the current approaches to building's greening and sustainability this paper outlines the intrinsic harmony of the traditional village houses encompassing efficiency and balanced use of renewable materials and energy sources. Further paper reviews technical advances in integrating energy efficiency, solar and other renewable energy sources in new and existing buildings, to approach...
In this paper an off-grid hybrid energy system consisting of a reverse osmosis desalination plant for brackish water powered by renewable energy sources, and a diesel generator as back-up will be described. The whole system serves as a prototype for testing new automatic control methods to increase the plant reliability, which is crucial in remote arid areas. The necessary steps for the design of...
The current feed-in tariff system for renewable energy sources and cogeneration in Croatia stimulates privileged producers exclusively for electricity delivered into the grid, both on transmission and distribution levels. Hence, the electricity consumed on the power plant site is not stimulated by the current feed-in tariff system. Therefore, most privileged producers, in order to receive incentives...
This paper addresses unit commitment for micro-grid optimization including renewable sources, working under deregulated power market. As micro-grid supplies both of heat and electricity consumer, operational optimization must be done in coordination. So far in this paper, renewable energy sources are considered to be negative load, and batteries, as well, are used as the load flattened device to raise...
Renewable and nonconventional distributed energy resources (DERs), such as, wind, solar PV, microturbines, fuel cells, diesel generators etc. are gradually becoming more popular as energy efficient and low-emission energy sources. Recent deregulation initiatives in power and energy industry are currently influencing company decisions regarding the construction of new generation plants and transmission...
The integration of distributed generation (DG) and renewable energy sources (RES) in the passive controlled distribution networks leads in present situation to an expansion of the network capacity and thus to excessive investments. If no measures will be taken these expenditures will increase in proportion to the growth of DG&RES. The virtual power plant (VPP) anticipates these challenges and...
