Due to the defects of the way of the traditional grid power supply, microgrid arises at the historic moment. At present, DC microgrid is an effective solution to integrate renewable energy sources which are DC power supply with DC loads. In allusion to the power unbalance intra-microgrid and the wide fluctuation of DC bus voltage due to unstable output of DC micro resources in DC microgrid, A DC microgrid...
In this paper, authors report on that the peak cut/peak shift operation could reduce the fluctuation range of utility power. Authors have created a small micro grid and are engaged in studying its multifaceted characteristics. In this paper, it has developed the Peak cut / Peak shift operation using tie line power flow control in AC/DC micro grid.
This paper focuses on the design and control of a stationary energy storage system based on multiple modular high voltage battery modules. The system achieves bi-directional power flow directly from 400V dc grid to the 12V battery modules via a bi-directional dc-dc converter with high conversion ratio as an interface. One merit of such a system is its extensibility and scalability for higher power...
The number and variety of electric vehicles connected to grid continue to grow rapidly, which results in a heavy burden on grid. To solve this problem, the concept of V2G (Vehicle to Grid) that electric vehicles could act as a new power source for grid was proposed. With distributed renewable energy developing fast recent years, charging EVs is a good way to use it. The DC micro-grid program being...
