A scalable multi-agent paradigm is presented for control of distributed energy resources to achieve higher reliability, higher power quality, and more efficient (optimum) power generation and consumption A dynamic hybrid multi-agent system is proposed in this paper as a means to achieve scalability for control of a large network of power generation, transmission, load, and compensation sources....

More than a decade of research in the field of thermal, motion, vibration and electromagnetic radiation energy harvesting has yielded increasing power output and smaller embodiments. Power management circuits for rectification and DC–DC conversion are becoming able to efficiently convert the power from these energy harvesters. This paper summarizes recent energy harvesting results and their pow...

The integration of the two is a key on introducing workflow technology in the application systems. However, an inappropriate method easily results in invasive system code, structural damage, tight coupling system, and reduces the flexibility of the systems, increases the difficulty to maintain. Then two integration models were presented, and a new integration method was brought the implementati...

Safecast is a volunteered geographic information (VGI) project where the lay public uses hand-held sensors to collect radiation measurements that are then made freely available under the Creative Commons CC0 license. However, Safecast data fidelity is uncertain given the sensor kits are hand assembled with various levels of technical proficiency, and the sensors may not be properly deployed. Ou...

The electric power system is an important infrastructure that plays the important role in the economical status of a nation. It is, therefore, very important and useful to design a green energy distributed power system .This paper presents the concept of power management strategies of a green energy distributed power system .The green energy distributed power system is one way to assure self-he...

Low power is a primary concern in the field of wireless sensor networks. Bluetooth has often been labeled as an inappropriate technology in this field due to its high power consumption. However, most Bluetooth studies employ rather over–simplified, fully theoretical, or inadequate power models. We present a power model of Bluetooth including scatternet configurations and low–power sniff mode an...

Self-managed middleware should be able to manage resources transparently and cost-effectively, while hiding the underlying complexity from users. Our group at the Barcelona Supercomputing Centre (BSC) and Technical University of Catalonia (UPC) has strengths in a diverse set of research areas, and through cross-disciplinary studies is building middleware that has the additional crucial feature ...

Industries having poor power factor face the problem of reduced power quality and increased electricity charges. To improve the power factor, capacitor banks of appropriate KVAR ratings are to be placed. In this paper the inductive loads in a sugar mill are investigated and suitable power factor improvement capacitors are recommended. The effect of low power factor on distribution losses and KV...

Maximum power point tracking (MPPT) is one of the key functions of the solar power management system in solar energy deployment. This paper investigates the design of fuzzy-logic-based solar power MPPT algorithms using different fuzzy input variables. Six fuzzy MPPT algorithms, based on different input variables, were considered in this study, namely (i) slope (of solar power-versus-solar volta...

reactive power management plays an essential role in the secure operation of the power system as an ancillary service. although in electricity markets, the particular attention is paid to active power, the reactive power also plays an important on total generation costs of electricity. on the other hand, as it is mainly confined to local consumption, to avoid market power and maintain the secur...
