in this paper, an attempt has been made to introduce a new control strategy including plug-in hybrid electric vehicle (phev) and diesel engine generator to control the voltage and frequency of autonomous microgrids. the proposed control strategy has multiple advantages over the recent control methods in microgrids. the proposed method applies the primary and secondary frequency control strategy...
One of the major and more challenging problem that is going to affect the future electricity system is the one relate to the frequency stability and support from generating units. In traditional power networks frequency support were transiently provided by the rotating mass of the generator (directly connected to the grid) while the steady state contribution to frequency is provided by a droop ...
New features like high penetration level, low inertia, and weak damping are decreasing voltage support capacity in the power system as it sees large-scale renewable energy source (RES) integration continuously. The reasonable solution to this challenge is developing an additional active regulation function for converters (VSCs). This study proposes a droop-based control strategy VSCs RES-integr...
Along with the sustained growth of photovoltaic (PV) penetration, PV generation is expected to be more active in DC microgrids rather than maximum power generation. The droop control methods are generally adopted achieve regulation at steady-state and passive power-sharing transient state. However, traditional <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://ww...
E-mail address: [email protected]; [email protected] Abstract This article presents the development of an optimized droop controller of microgrid during islanding using artificial fish swarm algorithm (AFSA). This is necessary in order to minimize the frequency deviation that occurs when microgrid switches to stand-alone mode or when there are changes or variation in loads. The optimize...
A droop-free nitride light-emitting diode (LED) with the capacity to operate beyond the "green gap" has been a subject of intense scientific and engineering interest. While several properties of nanowires on silicon make them promising for use in LED development, the high aspect ratio of individual nanowires and their laterally discontinuous features limit phonon transport and device performanc...
