Abstract-This paper presents a comprehensive simulation study of PI Controlled Three phase Series active power filter to improve power quality. The series active power filter employs a method for the reference compensation current based on Fast Fourier Transform Passive, L-C filters have disadvantage of fixed compensation and not fit for fast varying condition while by using auto tuned active p...

A possible detrimental effect of onshore series compensation in the GB grid is the appearance of subsynchronous resonance (SSR). In this paper, a control scheme for a VSC-HVDC link capable of damping subsynchronous oscillations is proposed in order to effectively counteract the potential damage caused by SSR in steam turbines. The VSC-HVDC link has been modelled to maintain its primary function...

A scalable multi-agent paradigm is presented for control of distributed energy resources to achieve higher reliability, higher power quality, and more efficient (optimum) power generation and consumption A dynamic hybrid multi-agent system is proposed in this paper as a means to achieve scalability for control of a large network of power generation, transmission, load, and compensation sources....

This paper presents a procedure for voltage stability margin evaluation under line outage condition considering static voltage stability limit. The proposed methodology is carried out in three steps. The first step of the study mode consists of obtaining sensitivity relation which relate loadability margin with real and reactive power injections at buses. In step two line outage is simulated us...

I have implemented a new scheme for describing real-time controllers. A system in this scheme consists of a set of concurrently-executing modules communicating through single-sender, multiple-receiver unbuffered channels. Intended for discrete, reactive systems, this scheme employs the synchronous model—computation and communication is instantaneous. Instantaneous computation simplifies reasoni...

Considering the advantages of DC microgrids, the extension of the conventional AC distribution grid can be implemented using a DC microgrid. This justifies the realization of a hybrid AC/DC microgrid. In the present study, a new global solution is presented to improve the power quality and to fully compensate the reactive power of an AC microgrid using DC bus capacity while introducing a new de...

This paper explores the performance of a simple model agent using a reactive controller in situations where, from an external perspective, a solution that relies on internal states would seem to be required. In a visually-guided orientation task with sensory inversion and an object discrimination task a study of the instantaneous response properties and time-extended dynamics explain the non-re...

This paper presents a regenerative cascade inverter topology with direct active power control scheme. From the mathematical model of the proposed regenerative cascade inverter, the instantaneous active power and reactive power are derived. Based on the instantaneous abc theory, direct active power feed-forward control is proposed to reduce AC power and voltage fluctuation in DC link. Moreover, ...

A necessary consequence of the nature of neural transmission systems is that as change in the physical state of a time-varying event takes place, delays produce error between the instantaneous registered state and the external state. Another source of delay is the transmission of internal motor commands to muscles and the inertia of the musculoskeletal system. How does the central nervous syste...
