This paper gives the State Space modeling of Distribution Static Synchronous Compensator (D-STATCOM). It is important to keep the voltage constant in the distribution system, hence voltage regulation is required in the distribution network. Voltage Source Converter (VSC) based D-STATCOM achieves voltage regulation in the connected bus by absorbing/supplying the required reactive power. The capability...
The obvious increment in carbon dioxide emission has encourage the power converters designers to enhance designs in order to guarantee the use of green power generation technologies. It should be balanced the fact that we need to decrease carbon dioxide emissions with the fact that we need to ensure that all power system technologies asure system stability, robustness and reliability. A useful power...
The STATCOM (Synchronous Static Compensator) based on VSC (Voltage Source Converter) is used for voltage regulation in transmission and distribution systems. The STATCOM can rapidly generate or absorb dynamic reactive power during system faults for voltage regulation. Strict requirements of STATCOM loss and total system loss penalty preclude the use of PWM (Pulse-Width Modulation) for STATCOM applications...
Many types of microgeneration technologies are interfaced with the low-voltage distribution network through power electronic converters. The converter provides conversion of the microsource frequency to the conventional power system frequency of 50/60 Hz, and controls the power exchange between the generator and the load/utility system. A power factor control strategy is presented, which demonstrates...
It has been mentioned in the literature that, among the multilevel inverter topologies used for STATCOM applications, the cascaded multilevel topology is the most advantageous and economical one. On the other hand, the main problem of this topology comes out to be the difficulty of sustaining the DC capacitors' mean voltages. This issue is very important for obtaining an output voltage with low THD...
The present research study is focused on the design, development and validation of a device based on multilevel converter for medium voltage distribution networks. It regulates the reactive power exchanged with the grid (up to 3 MVAR), allowing to achieve the following objectives: Network voltage regulation, reactive power compensation and power factor control. The device is composed by an IGBT based...
