“…Thus, here multiphase boost converters are used instead of conventional boost converters. By using these converters, generated ripple, size of inductor and power loss of switches can be decreased and reliability can be increased also the possibility to increase energy efficiency can be provided [29][30][31][32][33][34][35][36][37][38]. …”

This paper presents a robust nonlinear integrated controller to improve stability of hybrid AC/DC micro-grids under islanding mode. The proposed controller includes two independent controllers where each one is responsible to control one part of the system. First controller will improve the stability of input DC/DC converter. Using this controller, the voltage of DC bus is fully stabilized such that when a large disturbance occurs, its voltage will become constant without any significant dynamic. The necessity of DC bus regulation which has not been considered in previous studies, is imminent as it not only improves voltage stability of the micro-grid but also protects consumers which are directly connected to the DC bus, against voltage variations. Frequency stability of the micro-grid is provided by the second proposed controller which is applied to output DC/AC converter of the micro-grid. Adaptive method is used to make the controllers proposed in this paper, robust. Duty cycle of converters switches are adjusted such that voltage and frequency of the micro-grid are set on the desired value in minimum possible time under transient disturbances and uncertainty of the loads as well as micro-sources characteristics.

BioH2 &Amp; BioCH4 Through Anaerobic Digestion

Microbial fuel cell (MFC) technology can be employed in order to add value to the metabolic products of acetogenesis fermentation after H 2 production. Considering the total conversion of glucose into acetic acid as the only bioproduct, only 1/3 of the energy available is converted in H 2 from a thermodynamic point of view (Chap. 5). Furthermore, in practical terms, the energy necessary to carry out the pretreatments must be considered as energy used to perform the energy balance, in order to render the organic contents accessible to microorganisms (Chap. 9). Nevertheless, the aim of this book is to focus on anaerobic technology and its energy sustainability; the conversion of H 2 production residues, such as VFA, into additional H 2 or CH 4 or electricity needs to be investigated. Even if the MFC technology is in its infancy, it deserves a very close attention for the possibility of generating electrical energy or additional H 2 . The present chapter is devoted to explore the potential of MFC technology.

“…Benziger et al [6] noted that previous researchers had overlooked a decisive factor in the determination of the MPP, i.e., the external load. By adding a variable load to the base external load to achieve increased power output, they found that changing the external load impedance was a more effective method to alter the power delivery.…”
