Combined with the operation characteristics of photovoltaic power generation system, mathematical model and simulation are established, control strategy bipolar inverter wide output maximum point tracking (MPPT) method conductance increment designed. The stable distributed system realized. results show that established in this paper can effectively reflect MPPT control. With change lighting con...

A graph generator is a tool which allows to create graph-like data whose structural properties are very similar those found in real world networks. This paper presents two methods generate graphs with power-law edge distribution based on the MapReduce processing model that can be easily implemented run top of Apache Hadoop. The proposed allow generation directed and undirected distributed witho...

Development of distributed generations’ technology, trends in the use of these sources to improve some of the problems such as high losses, low reliability, low power quality and high costs in distributed networks. Choose the correct location to install and proper capacity of these sources, such as important things that must be considered in their use. Since distribution networks are actu...

The droop control strategy is the most common approach for microgrids control but its application is limited due to frequency deviation following a load change. Complementary control strategy has then been proposed to solve the problem using a communication network. However, under this strategy, regular loads profile produces a continuous change of output power of all distributed generators (DG...

fuel cells belong to an avant-garde technology family for a wide variety of applications including micro-power, transportation power, stationary power for buildings and other distributed generation applications. the first objective of this contribution is to find a suitable reduced model of a solid oxide fuel cell (sofc). the derived reduced model is then used to design a state estimator. in th...
