Due to the constant trend of building wind turbine sets and photovoltaic cells, so-called renewable energy sources, it is important develop a mathematical model that will allow us analyse economic viability their operation. By using this model, multivariate calculations should be carried out developed in form universal nomograms estimate almost on an immediate basis. In paper, such for unit cos...

The aim of the article is to present idea ​​energy clusters and legislative changes concerning creation energy clusters. An attempt was made theoretically analyze concept in light amendment Act on renewable sources (RES). method literature review applied most important items functioning were referred to. Provisions subsequent RES laws regarding presented, starting from February 20, 2015, which ...

Compared to 2011 the global emissions of CO2 – supposedly the main cause of global warming – increased only by 1.1 % in 2012 (3% in 2011) but still reached an all-time high of 34.5 billion tons in 2012 [2]. Nevertheless the growth of renewable generation in the electricity system is remarkable. The share of renewable energy sources (RES) such as wind, PV (Solar) and Bio fuels is increasing with...

Renewable energy sources (RES) have potentials to address goals of climate change mitigation at the global level. Iran has abundant RES potentials and investment into renewable energy sources can contribute to its socio-economic development and to diversification of its energy mix. Economic and technical capacities but also human factors, such as stakeholders’ views, public and social acceptanc...

The main objective of the chapter is the development of technological knowledge, based on Matlab/Simulink programming language, related to grid connected power systems for energy production by using Renewable Energy Sources (RES), as clean and efficient sources for meeting both the environment requirements and the technical necessities of the grid connected power inverters. Another objective is...

This paper describes a method to characterize the fluctuating electricity generation of renewable energy sources (RES) in a power system and compares the different parameters for California and Germany. Based on this method describing the fluctuation and residual load, the potential contribution of grid-connected vehicles to balancing generation from renewable energy sources is analyzed for a 2...

The problems related to the differed time between production and use of electrical energy produced by renewable sources makes storage systems an integral part of Renewable Energy Sources (RES), especially for stand-alone systems. Furthermore, for grid-connected systems, the stability of the electric system and the quality and stability of the delivered voltage will result in a high quality syst...
