Recently, solar energy has been intensively employed in power systems, especially using the photovoltaic (PV) generation units. In this regard, paper proposes a novel design of fuzzy logic based algorithm for varying step size incremental conductance (INC) maximum point tracking (MPPT) method PV. proposed method, variable voltage is estimated according to degree ascent or descent power-voltage ...

The virtual synchronous generator (VSG) is a good solution for stabilizing the power system with high penetration of renewable energy. However, in case serious unbalanced voltage disturbance/fault, conventional VSG may lose voltage, inertia, and damping support characteristics to grid even can cause disconnection This paper proposes an improved fault control strategy coordination STATCOM. propo...

Over the course of the 20th century, the electrical power systems of industrialized economies have become one of the most complex systems created by mankind. A number of ongoing trends will drastically change the way this critical infrastructure is operated. Demand for electricity keeps growing while the controllability of generation capacity is decreasing due to introduction of renewable energ...

voltage control is one of the imperative issues in the smart distribution control system. while traditional distribution network is equipped with communication and monitoring equipment, the online voltage control can be perfectly achieved. with using these smart grid technologies, the distribution voltage control schemes should carry out intelligently and cover the undesirable effect of high pe...

Under the traditional droop control, hybrid energy storage system cannot take advantage of respective merits battery and supercapacitor for frequency coordination, which shortens life. Because single-phase inverter load, second harmonic current is generated in front-stage converter when output power pulsates at twice voltage frequency. This paper proposes a strategy coordination suppression bas...

Failure and circuit upset of electronic equipment due to transients is a problem now and is one which has promise of becoming more of a problem in the future as trends continue toward miniaturization and circuit complexity. Protection methods are used more or less extensively and often haphazardly. At present, there does not appear to be a clear approach toward achieving compatibility between t...
