This paper proposes a small wind energy conversion system comprises permanent magnet synchronous generator (PMSG), uncontrolled rectifier, conventional H-Bridge inverter and dc-dc bi-directional converter. The dc link capacitor is connected to a storage system through Bi-directional power flow link. A hybrid pulse width modulation (HPWM) controller is used to regulate the ac load voltage and fr...

The rapid uptake of natural gas-fired units in energy systems poses significant challenges coordinating the electricity and gas systems. Besides, uncertainty caused by integrated renewable such as wind power raises more requirements on robustness operation for system (IEGS). To address these challenges, this paper investigates distributed adjustable robust optimal flow (OPGF) model IEGS. Using ...

This paper deals with Voltage and frequency controller for wind generating system with unbalanced linear loads. The proposed system is modelled and simulated in MATLAB using simulink .The controller that controls both voltage and frequency of an asynchronous generator along with its improvement of power quality. The proposed controller has bidirectional active and reactive power flow capability...

Solving the power flow problem in a distributed fashion empowers different grid operators to compute overall state without having share models—this is practical which industry does not have off-the-shelf answers. We propose two physically consistent formulations (a feasibility and least-squares formulation) amenable solution methods from optimization: Alternating direction method of multipliers...

In this paper a new optimization algorithm, the biogeography based optimization (BBO) is employed to design a robust power oscillation damping (POD) controller using unified power flow controller (UPFC). The controller that is used to damp low frequency oscillation is designed over a wide range of operating points using two different objective functions. The obtained controllers are then verifi...

This paper compares four converter topologies for the implementation of flexible ac transmission system (FACTS) controllers: three multilevel topologies (multipoint clamped (MPC), chain, and nested cell) and the well-established multipulse topology. In keeping with the need to implement very-high-power inverters, switching frequency is restricted to line frequency. The study addresses device co...

Over the past decade, Internet of Things (IoT) has undergone a paradigm shift away from centralized cloud computing towards edge computing. Hundreds billions things are estimated to be deployed in rapidly advancing IoT paradigm, resulting enormous amounts data. Transmitting all these data recently proven performance bottleneck, as it causes many network issues relating latency, power consumptio...
