  1. AN ANALYTIC METHOD FOR TWO-PORT PASSIVE NETWORK COMPUTING FOR ANALYSIS OF COUPLED OSCILLATORS
    Mihai IORDACHE, Lucia DUMITRIU, Lucian MANDACHE, Dragos Niculae, Jean-Marie PAILLOT (Franta), David CORDEAU (Franta)

    Voltage controlled oscillators are present in the most of the digital communication system. In our days, they are used to control the phase in microwave antenna arrays. Researches are made so that a particular phase shift can be obtained by choosing the fre…

  2. POWER SYSTEM OPERATION IN A CHANGING ENVIRONMENT
    Walter Sattinger (Elvetia)

    Currently worldwide all power systems are faced with dramatically changes. After restructuring the system operation due to unbundling and deregulation and related high volatility of power flows at the level of transmission, we can observe substantial change…

  3. VECTORIAL PROBABILISTIC MODEL FOR THE UNBALANCE FACTOR OF A THREE-PHASE ELECTRICAL NETWORK
    Lambert Pierrat (Franta)

    In a three-phase power electrical network, the voltage asymmetry can be split into two different components. The first component results from the network structure and possesses almost constant value caused by asymmetry of circuit elements (e.g., lines, tra…

  4. ENERGY MANAGEMENT SYSTEM OF HYBRID MICROGRID WITH ENERGY STOR
    MSc. Mousa MARZBAND, MSc, Assoc. Prof. Andreas SUMPER, PhD - Spania, Prof. Mircea CHINDRIS, PhD, Assoc. Prof. Bogdan TOMOIAGA PhD

    The economic scheduling of the generation units is playing a significant role in the energy management of the hybrid stand alone microgrid. Energy storage is an increasingly important part of the renewable energy sector because of the need to store power dur…
