This paper presents a new method for operating microgrid, which is formed by one droop controlled and other two PQ controlled distributed generators (DGs). The reference power of droop-controlled DG is adjusted by a multiplying factor, which is produced from the voltage variation. By doing so, the dynamic balance of the system can be reached swiftly. The inverter topology is voltage source inverter...
In order to control the high-density hole carrier in hydrogenated diamond surface, diamond FETs using AlN/diamond heterojunction structure and high-k gate oxide dielectric are demonstrated.
This paper proposes an operation optimization model for micro-turbine based Combined Cooling, Heating and Power(CCHP) systems. The proposed model is adopted to analyze CCHP systems to minimize the operating cost, and takes accounts of the electricity pricing method and interactive mode with the network. Under spot price, the economy of the CCHP system is analyzed and compared with a decentralized...
An increasing number of Internet applications and services render network management more troublesome for bandwidth misuse and security concern. As a result, network traffic identification plays an increasingly important role in network management. Deep packet inspection (DPI) is one of the effective approaches. Conventional network devices lookup the header of a packet, but DPI means the network...
