For more than 30 years, Lebanon has suffered from insufficient electric production. While the world is shifting towards total dependency on renewable energy, Lebanon is still facing the disastrous situation in its electricity sector. This paper suggests a plan of building diesel power plants and engaging them to the public grid. To achieve this, a supervisory control method (SCM) including a frequency...
Distributed Generation is the generation of electricity from many small energy sources and is located closer to the user, or customer. The purpose of using distributed generation is to improve voltage profile, voltage stability and to minimize power losses. This paper presents an overview of research and development work carried out in the field of Distributed Generation. This paper also discusses...
In the year 2007, South Africa experienced high demands of electricity power than that could have been generated. Due to greater demand than the generation, the country experienced planned and unplanned load shedding. Hence the commercial operations, industrialization country's economy and mostly people's life styles were highly affected. The unplanned load growth, indiscriminate integration of distributed...
This paper seeks to further proposals previously submitted for a balanced Distributed Generation strategy through modified MicroGrids as part of the various regional energy programs underway in Africa. Developing a sense of ownership at the local community level in a strategic collaboration with the university body and technical schools is the key for the success of projects. In addition to the technology...
The distributed resource energy has been widely used to cope with the higher demand for power quality. The association of different Distributed Generation System (DGS) could cause as many problems as it may solve. The generation and loads could be considered as a micro-grid and separate from the distribution system to isolate the micro-grid's load from the disturbance without harming the distributed...
As the requirement for the power quality is increasing nowadays, the distributed source energy has been widely used. The association of different Distributed Generation System (DGS) could cause as many problems as it may solve. Micro-grid associates the distributed generation and the loads as a subsystem. The generation and loads could separate from the distribution system to isolate the micro grid's...
It is known that the increasing penetration of Distributed Generation (DG) implies different technical problems in the operation of distribution systems. This paper focuses the electrical Power Quality (PQ) aspects. DG can be responsible for different PQ problems, like poor voltage quality, unwanted protection trips on healthy feeders, and “islanding”. Voltage quality, in particular, can become a...
This paper describes some of the aspects of the Smart Grid Initiative in the US and purports its realization through an emerging paradigm in microgrids, i.e., the customer-driven microgrids. Special attention is paid to the increasing role played by energy storage elements. Some existing technologies of energy storage are revisited in the perspective of their utilization in customer-driven microgrids.
The connection of distributed generation, mainly at the lower voltage levels, is transforming the legacy network. The evolution of the network has to overcome the problems associated with the integration of distributed generation. These problems include the management of the network's voltage, reactive and active power flows, fault current, power quality, and frequency and voltage stability issues...
This paper presents the effect of distributed generation (DG) in voltage variation and losses on very long distribution line with multiple voltage regulator. This paper considers the operation of DG effected voltage along distribution and power loss when varying load. From this study the operation of DG has effected to voltage along the very long distribution line depended on load varying and location...
This paper presents the effect voltage variation from distributed generator (DG) on long distribution line with multiple voltage regulator. The mini hydro power plant is used as distributed generator. This paper considers the operation of DG and automatic voltage regulator (AVR) effected voltage along distribution on varying load. From this study, the operation of DG and AVR has effected to voltage...
The distributed energy resources customer adoption model is used to estimate the value an Oakland nursing home, a Riverside high school, and a Sunnyvale data center would need to put on higher electricity service reliability for them to adopt a consortium for electric reliability technology solutions microgrid (CM) based on economics alone. A fraction of each building's load is deemed critical based...
Distributed generation (DG) is finding its way into the worldwide distribution networks very rapidly. As the existing networks were not created for this new structure of electricity production, the preservation of a reliable network operation and a high level of power quality is a big challenge for all network operators. In a study conducted by the University of Erlangen and the Erlanger Stadtwerke...
An overview is given of the various energy storage technologies which can be used in distributed generation (DG) schemes. Description of the recent photovoltaic DG initiative in Singapore is included, in which several of the storage systems can find ready applications. Schemes pertaining to the use of solid oxide fuel cell for power quality enhancement and battery energy storage system used in conjunction...
The paper presents a new technique to mitigate the voltage unbalance in LV distribution grids using distributed generation (DG). Usually, public LV networks supply many single phase consumers; in this case, the unbalanced line currents produce the unbalance of standard symmetrical supply voltage system. This voltage system negatively influences other three-phase loads operating in the same system,...
Fuel cell systems have generated significant interests in residential applications as well as distributed power generation due to their cleanliness, portability and suitability for electricity and heat generation. Development of a suitable power electronic interface to make the technology viable is still a challenge. This paper presents a single stage power electronic interface for fuel cell power...
