Newton Power Flow Modeling of Voltage-Sourced Converter Based HVDC Systems

This paper deals with the application of an autonomous Self-Excited Induction Generator (SEIG) in a small wind power conversion system (WPCS). Such conversion system has capability to supply power demand of the loads with constant voltage and frequency, for which a power managing method is proposed. Voltage Sourced Converter (VSC) along with Battery Energy Storage System (BESS) is used to handle power flow between the SEIG and loads. The proposed control scheme, using a single voltage closed-loop control, is found to be suitable to regulate both voltage and frequency. The WPCS is modelled in MATLAB/Simulink and Power System Block-set (PSB). Simulation results show that Voltage Frequency Controller (VFC) has ability to keep the voltage and frequency constant in spite of perturbations.

Magnetic Energy Storage

Unified Power Flow Controller (UPFC) is a Voltage sourced converter based Flexible A.C.Transmission (FACTS) controller which has a capability of simultaneously or selectively controlling all the parameters affecting transmission of power. With emphasis on harnessing renewable energy many energy storage technologies are being used. Superconducting magnetic energy storage (SMES) stores energy in magnetic form by means of a D.C. current circulating in a superconducting coil. To exchange power with SMES a power electronic interface is required. Feasibility of interfacing SMES to D.C. link of UPFC has been explored in this paper. A multimachine system with a long transmission line is compensated by UPFC-SMES .A DC-DC chopper modulates power of SMES so as to improve the transient stability of system. Complete simulation has been done using MATLAB/Simulink which shows improvement of first peak, damping of oscillations & improvement in critical clearing time.
