The Unified Power Quality Conditioner (UPQC) is a technology that has successfully addressed power quality issues. In this paper, photovoltaic system with battery storage powered presented. Total harmonic distortion of the grid current during extreme voltage sag and swell conditions more than 5% when UPQC controlled synchronous reference frame theory (SRF) instantaneous reactive (PQ) control. s...

In this paper, a novel control method for photovoltaic converter connection to the national gridis presented, so in addition to the injection control by solar arrays to the grid, this method cancompensate reactive power and harmonics in the load current. The system will be connected inparallel between the grid and load. The proposed system supplies all load power consumption(including active po...

Wind and solar energy systems are among the most promising renewable technologies for electric power generations. Hybrid (HRES) enable incorporation of more than one technology, allowing increased reliability efficiency. Nevertheless, introduction variable generation sources in concurrence with existing system load demand necessitates maintaining balance between components HRES. Additionally, e...

Electronic power converters connected to electrical grids allow industrial processes, traction applications and home appliances to be improved by controlling the energy flow depending on the operation conditions of both the electrical load and the grid. This is the case of variable frequency drives, which can be found in pump drives or ship propulsion systems (Bose, 2009) maintaining the electr...

: In this paper, the operation of a future distribution network is discussed under the assumption of a multi-carrier microgrid (MCMG) concept. The new model considers a modern energy management technique in electricity and natural gas networks based on a novel demand side management (DSM) which the energy tariff for responsive loads are correlated to the energy input of the network and changes ...
