Distributed Generation (DG) system is a futuristic step towards generation of electrical power energy. It is treated as a microgrid, which is integrated with renewable energy resources. The successful implementation of DG in ac distribution system depends on the Power Quality (PQ) of generation. The power conditioning or the power quality of the microgrid is accomplished by Unified Power Quality Conditioner...
The development of distributed generation system and electric vehicles is bound to strain the distribution network. A typical radial distribution feeder suffers from voltage fluctuation and feeder overload in the presence of a large amount of variable renewable generation. This paper presents a concept of enhancing the power handling capacity of distribution networks using dc grid interconnections...
Three-phase self excited induction generator (SEIG) is increasingly getting attention for its use in distributed electricity generation and consumption viz wind, mini/micro hydro, biogas etc. The major advantage of induction generator over alternator includes its low cost, easy construction, ruggedness, maintenance free structure etc, whereas, varying demand of reactive power and poor voltage regulation...
In this paper, a new power sharing control method for a microgrid with several distributed generation units is proposed. The presence of both inertial and non-inertial sources with different power ratings, maximum power point tracking, and various types of loads pose a great challenge for the power sharing and system stability. The conventional droop control method is modified to achieve the desired...
The integration of distributed energy resources (DES) with the distribution network offers a number of technical, environmental, and economical benefits. This paper demonstrates the functions of a series grid interconnection module that integrates distributed generations (DG) and energy storage (ES) for peak load shaving and power quality enhancement. The proposed module uses a voltage source converter...
One of the problems emerging with a rising share of distributed generation (DG) is also the regulation of voltage levels in different operating conditions. Distribution network voltage profile can be controlled with the use of active compensators and also with converters which are used for connection of DG. Both devices are usually based on a voltage-source converter with a capacitor or DC source...
