The Photovoltaic (PV) plants are significantly different from the conventional synchronous generators in terms of physical and electrical characteristics, as it connects to the power grid through the voltage-source converters. High penetration PV in power system will bring several critical challenges to the safe operation of power grid including transient stability. To address this problem, the...
This paper presents a new approach for single-phase shunt active power filter with LCL output filter based on the two-loop control theory. In this method unlike the conventional two loop control, internal loop stability theorem with considering delay effect is studied. Moreover, an observer based on the Kalman-filter is combined with the proposed control scheme, to reducing the numbers of power...
The abrasion is a significant issue, especially in machining of rigid steels. A functional and suitable approach for enhancing the heat transfer from machining area is using an intermediate fluid with higher heat transfer potential instead of common fluids. The objective of this experimental study is to discuss production, stability and thermal conductivity examination of water/graphene oxide n...
