In this paper, a new topology is proposed for three-phase to single-phase matrix converters, where more voltage levels are produced in the output in comparison with the conventional topologies. In addition, a new control method based on minimum error between the generated and the desired output voltages is proposed for three-phase to single-phase matrix converters. In the proposed control metho...

In this project reduced switching losses and high efficiency is proposed for quasi resonant converter. An AC/DC quasi resonant converter with push pull topology is coupled to two distributed boost inductors into a single magnetic core which hereby reducing the circuit volume and the cost are the development targets of switching power supply today. The quasi resonant converter has ideally zero s...

As technology develops, the rapid increase in PV capacity will affect grid. This makes it important to determine limit that can be injected into grid defined as Hosting Capacity (PVHC). In this paper, author evaluates and analyses impact of connections on medium voltage distribution lines (20kv) using ETAP 19.01 simulation. A Grid with a 30MVA, has an industrial load varies from 650 kVA 25 tota...

The recent trends in electrical power distribution system operation and management are aimed at improving system conditions in order to render good service to the customer. The reforms in distribution sector have given major scope for employment of distributed generation (DG) resources which will boost the system performance. This paper proposes a heuristic technique for allocation of distribut...

The progression towards smart grids, integrating renewable energy resources, has increased the integration of distributed generators (DGs) into power distribution networks. However, several economic and technical challenges can result from the unsuitable incorporation of DGs in existing distribution networks. Therefore, optimal placement and sizing of DGs are of paramount importance to improve ...

VAR support should be supplied as close to the load as possible to minimize transmission losses. For voltage control and for improvement of total power factor in a distribution system the circuit- breaker switched capacitor banks can be used. The problems with this solution are the voltage steps caused by the large sizes of the capacitor banks as well as the transients caused on insertion. Thyr...
