Due to uncertain photovoltaic (PV) power generation, analyzing the voltage stability of transmission networks with a large PV plant is challenging. The output critical factor in establishing penetration levels active when assessing loading capabilities. Therefore, this article contributes enhancing understanding how static synchronous compensator (STATCOM) could be used as part system network. ...

In this paper, we demonstrate a robust design of Monolithic Microwave Integrated Circuits (MMIC) using Taguchi Method. In accordance with Taguchi Method, noise factors, which are uncontrollable sources of variation, and control factors, which are available to control both the deviations and the mean-values by circuit designers were assigned to an orthogonal array. We simulated radio frequency (...

Newly developed tools and techniques are continuously established to analyze monitor power systems’ transient stability limits. In this paper, a model-based index for each generator is proposed from the synchronizing torque contributions of all other connected generators in multi-machine interconnected system. It new interpretation generator’s coefficient (STC) terms electromechanical oscillati...

Deep-water canopy-forming algae Gongolaria montagnei var. compressa and Ericaria zosteroides (Fucales: Ochrophyta) co-exist in mixed populations, the first taxa dominating at upper limit of distribution (20 m) second lower (40 m). This depth pattern is consistent with photosynthetic performances both taxa, E. showing higher efficiency (α) light saturation (Ik) compensation (Ic) than G. compress...

This paper proposes coordinated design of wide-area damping controller (WADC) in the presence renewable energy resources a large-scale power system. To tackle with constant and time-varying delays system, robust criterion based on H∞ has been used for WADC design. By using an auxiliary function Lyapunov function, conservatism linear inequality matrix (LMI) is reduced, such that larger delay mar...

The stability and security improvements of the grid-connected to wind energy conversion system (WECS) can be made by optimizing placement a flexible alternating current transmission (FACTS). This study discusses optimal one type WECS, namely doubly-fed induction generator (DFIG) with series shunt-FACTS control device called unified power flow controller (UPFC). DFIG UPFC connected grid dynamic ...

Nowadays, different power systems are connected to each other due technical and economic reasons form a complex developed network. Such networks measure send system data decision-making centers for control protection. This information transmission is accompanied by delay causes the performance of system’s damping controllers be affected. To improve dynamic stability, supplementary controller in...

The integration of distributed generators (DGs) with flexible alternating current transmission systems (FACTS) can improve the performance grid system. In this study, we determine location and optimal size one type DG, based on wind energy, a shunt-FACTS control device called static var compensator (SVC). voltage profile is increase power loss reduced due to an improvement in from maximizing lo...
