In order to increase the flexibility of a microgrid, the active power exchange between a microgrid and the utility grid as well as other microgrids need to be controlled properly. The voltage based control of a Smart Transformer allows the control of active power flow between a utility grid and a microgrid at the point of common coupling (PCC). This paper addresses the control of the active power flow between two microgrids in an islanded mode and also between two microgrids in the grid connected mode with and without encouraging the participation of the utility grid. Here, we utilize the voltage based control on a thyristor controlled on load tap changing transformer which makes the Smart Transformer concept even more smart. The thyristor based Smart Transformer at the PCC enables faster switching and minimizes the arcing problems of a normal on-load tap changing transformer. The distributed generation units in the microgrid should be equipped with a voltage-based droop control strategy which reacts on the voltage change, making the Smart Transformer an element that controls power exchange without the need for any communication to other elements in the microgrid. The experimental simulations performed in MATLAB/SIMULINK follow that a smart transformer allows the power flow control between two microgrids.

Power quality improvement can be done effectively by adding passive or active filters in series or parallel with the line. Active filters perform efficiently but it is not cost effective. Traditional passive filters are cost effective but they are permanently connected to the system and draw large amount of source current even under light load conditions. By using auto tuned filters, the passive filter components can be controlled according to load variations and hence required reactive power compensation along with current harmonic elimination can be done efficiently. Auto-tuned filter with TSC-TSR combinations is designed and simulated in MATLAB/SIMULINK using Artificial Neural Network controller and a new controller called Isin Ф controller. Performance of both the controllers are compared. Simulation results show that Isin controller performs fast because of its reduced complexity and also easy to implement. The THD has reduced to a great extent along with reactive power compensation there by reducing the reactive power issues in transmission and distribution networks. More »»

This paper presents an improved operation of the Custom power park with a newly proposed control algorithm for series active filter. Custom power devices operated for multiple customers in an industrial area form a common platform called custom power park (CPP). CPP delivers high quality high reliable supply than from the utility at different grades. The enhanced operation of CPP is proposed with GTO based static transfer switch, shunt and series active filters.The shunt active filter provides the harmonic and reactive power support for the park while voltage sag/swell and voltage harmonic mitigation is done by means of series active filter with a newly proposed control algorithm. The entire model of CPP is developed and operation is verified using MATLAB/ Simulink model. More »»
