The publication presents the results of analysis of possible local benefits factored in utility scale wind energy for a remote location. Electricity is one of the most vital problems on the Earth, thus utility scale wind and solar energy devices are boosting economic development. Energy demand is constantly increasing, despite efforts to ensure the energy efficiency of devices. People are looking for more energy and electricity to consume. Although wind energy is still being researched and improved, modern generation of wind energy is becoming more and more effective and desirable. This publication presents an effective solution to this issue. It deals with the generation of green environment friendly electricity from wind turbine. The genuine idea is to provide energy for remote location using onshore wind turbines. An analysis of the demand for energy at a remote location and electricity consumption was made to provide preliminary calculations of the wind farm. The number of required turbines is determined taking into account all related factors. A specific wind turbine has been selected and proposed to provide the necessary location with the necessary amount of energy. The analysis carried out showed that the produced energy is environment friendly since there is no carbon dioxide emission.

W artykule przedstawiono wyniki badań eksperymentalnych i analizy efektywności energetycznej instalacji fotowoltaicznej o mocy 5,5 kWp zintegrowanej z dachem, pracującej w systemie on-grid. W rozważaniach uwzględniono średni dzienny czas pracy, średnią gęstość mocy promieniowania słonecznego i temperaturę na powierzchni modułów, a także zachmurzenie. Określono wartość energii elektrycznej wytwarzanej przez instalację fotowoltaiczną w okresie maj-wrzesień w skali miesięcznej, i w wybranych czasokresach doby.

The article presents results of an experimental research and an analysis of the energy efficiency of a 5.5 kWp photovoltaic roof installation working on-grid. Considerations included average daily working time of the PV system, average solar power density and temperature on the surface of the modules, as well as cloudiness. The value of the electricity produced by the photovoltaic installation from May to September was determined, per month and in selected time of the day.

Rapid Start units present high generation cost, so they are not usually online, but good dynamic response, so they are very suitable for AGC operation. The startup process of these units is very fast so they can be online and providing regulation within just a few minutes. In this paper a simple algorithm is presented to determine when to start up an offline rapid start unit to provide AGC service. The algorithm is tested using real operation data, with successful results. How to select the most appropriate values for the algorithm parameters is also analyzed in the paper.
