Optimal Sizing and Location Identification of Suitable Compensator in a Radial Distribution Network through Fuzzy- Flower Pollination Optimization Algorithm

Abstract: The primary goal of distribution networks is to transfer uninterrupted power supply between utility and utility customers with greater quality. The control of real power transmission loss and maintaining the bus voltage within the permissible range are considered to measure the quality of power delivery by the utility. In recent years, strategies such as reconfiguration, capacitor placement and Distributed Energy Resources (DER) placement are practiced for improving the power delivery performance of the distribution system. Furthermore, the placement of Flexible AC Transmission System (FACTS) devices such as series and shunt controllers are also used for line and load compensation in the power system for performance enhancement. In this research work, the performance analysis of three types of the FACTS devices such as Static VAR Compensators (SVC), Thyristor Controlled Series Capacitor (TCSC) and Unified Power Flow Controller (UPFC) have been carried out with the support of hybrid Fuzzy-Flower Pollination Optimization Algorithm (FFPOA). The FPOA identifies the optimal size and location of suitable FACTS devices in a distribution system for optimizing the Total Operating Cost (TOC) and bus voltage improvement. In addition, heuristic fuzzy is integrated for the effective handling of the multi-objective problem on distribution system optimization. The efficiency of the proposed hybrid algorithm is validated with the three standard benchmark test cases.

Multiple single input change test vector for BIST schemes

Abstract: In VLSI Industry testing is an essential process for making the assurance functionality of the chip. This paper is focusing one of the test methodology called built-in-self-test (BIST). To introduce a novel test pattern generator (TPG) called multiple single input change (MSIC) TPG for test the modules of the chip. This TPG generates single input change (SIC) test vectors in multiple scan chains. Scan chains count is equal to the number of modules inside the chip. MSIC test vectors are generated here with a re-configurable Johnson counter and a fixed seed values. Seed is a pre-defined bit for MSIC pattern generator based on the modules available in the chip. Bit EX-OR operation is performed between the Re-configurable Johnson counter and the seed. Analysis result shows that the produced MSIC sequences have the features of uniform distribution and low transition density. Simulation results with S344 benchmark demonstrate that MSIC can save the test power by 7.5%.
