This paper designs an energy allocation scheme based on maximum flow modeling for a microgrid containing renewable generators and consumer facilities. Basically, the graph consists of set nodes representing consumers or as well weighted links amount generation, consumer-side demand, transmission cable capacity. The main idea lies in that special node is added to account interaction with grid tw...

Abstract The purpose of this paper is to study how to apply distributed storage into a photovoltaic microgrid for rural villages with electrical network powered by renewable sources and small thermal generators. Using distributed storage helps to reduce Joule losses and voltage drops. This allows reducing the cable’s section or the power source’s size. The main work will focus on optimizing the...

The DC microgrid is an effective architecture that is utilized to achieve reliable power with high efficiency through the implementation of power electronics converters and energy storage devices. Many systems are currently using DC power. For instance, DC architecture is employed in data centers to provide efficient and reliable power distribution across large numbers of electrical loads. The ...

With the microgrid revolution, each house will have the ability to meet its own energy needs locally from renewable energy sources such as solar or wind. However, real-time data gathering, energy management and control of renewable energy systems will depend mainly on the performance of the communications infrastructure. This paper describes the design of a communication network architecture us...

This paper studies the fundamental problem of sizing energy storage given an uncertainty level of variable resources in a microgrid. A queuing theoretical model is introduced, which provides unique insights on the coupling between energy storage size and uncertainty level of the net load. The proposed model lends itself to 3 levels of details: a random walk model with single uncertainty from on...
