Keywords: fuel cells; ancillary services
Abstract: The paper aims to identify the current state of ancillary services consumption in power station.In order to replace current methods of supply internal services with, modern solutions based on renewable, clean solutions that exceed current system performance at the lowest cost.. In addition, it has been identified the main consumers of power stations in order to approach the implementation phase of a hybrid system in substations.

Abstract:This paper presents the analysis of producing an electric power of 2.8 MW using a solar photovoltaic plant. The PV will be grid connected to the distribution network. The study is focused on the influences of connecting to the grid of a photovoltaic system, using modern software for analysis, modeling and simulation in power systems.

Abstract: The grid of most countries is set up to be centrally controlled, but in last decade more researches explores solutions to gradual reorganization the power system to resemble the Internet. In this paper we discuss about emergent technologies for smart grids deployment with the focus on middleware for Internet of Things in the Cloud.

Abstract: In this paper, a small wind turbine is analyzed. Because usually the manufactures don’t provide enough information about the turbine (especially for small turbines), the steps for obtaining this parameters are presented. A Matlab program was written to fulfill this steps and then the whole turbine was simulated in Simulink. The resulted performance curve from simulation was compared with the performance curve from the manufacture’s datasheet for validation.

Abstract:The electrical power required by a house can be obtained either by producing it locally from various sources but also by connecting to the main grid. This article wants to provide a method to calculate the cost in the two situations, in order to choose the best option
