Combined with the operation characteristics of photovoltaic power generation system, mathematical model and simulation are established, control strategy bipolar inverter wide output maximum point tracking (MPPT) method conductance increment designed. The stable distributed system realized. results show that established in this paper can effectively reflect MPPT control. With change lighting con...

in this paper, the performance of two types of facts devices in order to enhance the power system static voltage stability has been investigated. these devices include static var compensator (svc) and thyristor controlled series capacitor (tcsc). the modeling of the single machine infinite bus (smib) and aforesaid devices has been made up in steady state mode with disregarding of the generator ...

Deregulation policy has caused some changes in the concepts of power system reliability assessment. This paper deals with generation reliability evaluation in perfect competition power market using market economic concepts and its dynamic. Also, because of power markets and generators’ forced outages stochastic behavior, Monte Carlo Simulation (MCS) is used in this research. Generation reliabil...

In this paper a comprehensive approach is presented to improve power swings damping based on direct Lyapunov method. The approach combines superconducting magnetic energy storage (SMES) system with static synchronous compensator (STATCOM). Considering the energy absorption/injection ability of SMES, in transient states the combination exchanges both active and reactive powers with power system....

Hybrid AC/DC microgrids facilitate the procedure of DC power connection into the conventional AC power system by developing the distributed generations (DGs) technologies. The conversion processes between AC and DC electrical powers are more convenient by hybrid systems. In this paper, an energy management system (EMS) for a hybrid microgrid network is proposed due to the optimal utilization of...
