The paper highlights on a new method to solve the network reconfiguration problem. The uncertainty of system loads vary from time to time and makes the distribution system operation and control more complex. Thus for a feeder system power loss is not at its minimum. In this context a methodology to reconfigure the microgrid and also to facilitate its operation in autonomous mode is being discus...

The most common problems encountered in any electrical distribution system are load unbalance and restoring service to healthy zones the case of a fault. on network is not constant varies from feeder throughout day. In event fault, reconfiguration performed balance loads restore zones. Network involves modifying structure by sectionalizing tie switches. Through reconfiguration, can be transferr...

Achieving fault-tolerance through incorporation of redundancy and reconfiguration is quite common. The distribution of faults can have several impacts on the effectiveness of any reconfiguration scheme; in fact, patterns of faults occurring at strategic locations may render an entire VLSI system unusable regardless of its component redundancy and its reconfiguration capabilities. Such fault pat...

-The paper presents one simple heuristic method for the reconfiguration of distribution networks in order to reduce the real power loss under normal operating conditions. The proposed me thod is computationally very efficient because it does not require the concept of optimal power flow and require less number of switching operations. The effectiveness of the proposed method is demonstrated thr...

Power losses issues persevered over few decades in the high demand utilization of energy electricity in developing countries. Thus, the radial structure of distribution network configuration is extensively used in high populated areas to ensure continuity of power supply in the event of fault. This paper proposes heuristic Genetic Algorithm known as SIGA (Selection Improvement in Genetic Algori...

This project presents two original implementations of improved accuracy current-mode multiplier and divider circuits. Besides the advantage of their simplicity, these original multiplier and divider structures present the advantage of very small linearity errors that can be obtained as a result of the proposed design techniques (0.9% and 0.75%, respectively, for an extended range of the input c...

With the consideration of randomness of distributed generations and loads, this paper has proposed a method for vulnerability assessment of microgrids based on complex network theory and entropy theory, which can explain the influence of the inherent structure characteristics and system internal energy distribution on the microgrid. The vulnerability assessment index is built, and the on-line r...
