The system of automatic control the reactive power factor enterprise's supply is considered, in which one part transformer substations equipped with adjustable capacitor units, and second not. Its advantage comparison shown, firstly, lower requirements for its error and, secondly, calculation consumer supplier electricity made taking into account ratio energy to active energy. An estimate regul...

The quality of service and the respect contractual characteristics voltage is a major issue transmission system operator. In this context, code requires that wind turbine participate in regulation voltage. Any variation must be compensated by producing or absorbing reactive power. This article studies modelling control strategies energy conversion based on doubly fed induction generator. It pre...

This paper proposes a novel wind energy conversion system based on a Five-phase Permanent Magnetic Synchronous Generator (5-PMSG) and a Five to three Matrix Converter (5-3MC). The low cost and volume and also eliminating grid side converter controller are attractive aspects of the proposed topology compared to the conventional with back-to-back converters. The control of active and reactive pow...

In this paper, dynamic performance of a transformerless cascaded PWM static synchronous shunt compensator (STATCOM) based on a novel control scheme is investigated for bus voltage regulation in a 6.6kV distribution system. The transformerless STATCOM consists of a thirteen-level cascaded H-bridge inverter, in which each voltage source H-bridge inverter should be equipped with a floating and iso...

The low voltage ride-through (LVRT) capability of the doubly-fed induction generator (DFIG) significantly impacts upon the integration of wind power into the power grid. This paper develops a novel comprehensive control strategy to enhance the LVRT and reactive power support capacities of the DFIG by installing the energy storage system (ESS). The ESS is connected to the DC-link capacitor of th...
