This involves having production units distribute to the consuming units through a single vertical and central distribution network. Each fl oor is served by an indirect connected substation (Figure 3). Enhancing comfort1 and reducing energy demand2 is possible when fl oorto-fl oor (rather than building-to-building) consumption is moderate (cooling) or low (heating) temperature radiant-based sur...

− The study presented in this paper aims to develop a new method for active and reactive power balancing in a four-wire stand-alone microgrid (MG), which feds single phase loads. Two unbalance compensation controllers are used, for active and reactive powers. The compensation is based on a dump load (DL) and a static compensator (STATCOM), which ensure the balance of the active and reactive pow...

This paper describes the characteristics and optimal methods for the planning of stand-alone microgrid system, in order to improve the power supply reliability, increase the coefficient of utilization of renewable energy and reduce the cost of investment and operation. Next, the problems in the optimal planning for a stand-alone microgrid system are summarized, including the unique operational ...

Abstract: Model predictive control (MPC) has been widely studied for regulating frequency in stand-alone microgrids (MGs), owing to the advantages of MPC such as fast response and robustness against the parameter uncertainties. Understanding the impacts of system parameters on the control performance of MPC could be useful for the designing process of the controller to achieve better performanc...

The identification of objects in video sequences, that is, video segmentation, plays a major role in emerging interactive multimedia services, such as those enabled by the ISOMPEG-4 andMPEG-7 standards. In this context, assessing the adequacy of the identified objects to the application targets, that is, evaluating the segmentation quality, assumes a crucial importance. Video segmentation techn...

Current tools for automated deduction are often powerful and complex. Due to their complexity there is a risk that they contain bugs and thus deliver wrong results. To ensure reliability of these tools, one possibility is to develop certifiers which check the results of tools with the help of a trusted proof assistant. We present a framework which illustrates the essential steps to develop stan...

The politics and purpose of health care accreditation programmes around the world have changed radically from the original models of North America 50 years ago. Then they were hospitalfocused, profession-driven, voluntary, self-financing and essentially non-governmental. The 1990s saw a rapid growth of programmes with an increasing emphasis on primary care, networks, health systems and regulati...

The stand-alone power inverter is equipped with various management systems which guarantee the stable operation of the power supply system. Battery, generator, power and load management complement each other to provide a comprehensive system management. All the necessary variables are measured or calculated by Sunny Island. This ensures that no switching activity or set point alteration will be...

Genetic testing uses advanced laboratory techniques to identify protein alterations, certain metabolites, chromosomes, or nucleic acids by which a genotype is determined or inferred. These tests provide insights into the molecular basis and physiopathology of genetic diseases, information which is critical for prevention, treatment and genetic counseling. Initiated in 1982, Cuba's National Prog...
