Abstract: Renewable energy resources are being used to overcome energy shortage. From the point of view of energy management the interconnectivity of electric utility with renewable energy resources is difficult. Renewable energy resources need to be managed with electric utility. A Smart Energy Management System (SEMS) is designed and developed for monitoring an efficient load management of electric utility and photovoltaic power system is presented in this research. The design consists of an Energy Management Center (EMC) and Field Programmable Gate Array (FPGA). Energy Management Center shows the runtime data and also keeps the data log and offers control of the load shifting between utility source and photovoltaic power system. Analog to digital converter is used to interface the current and voltage sensors with FPGA. ZigBee is connected for wireless radio data transmission between the FPGA and energy management & monitoring center. The SEMS increases the efficiency of energy up to 10.5 percent in comparison with normal systems.

Abstract: This paper presents a new approach to protect the transmission line by a design and implementation of distance relay using Fuzzy logic module. The proposed module uses sample of voltage and current signals to calculate line impedance (ZL). Simulation studies are performed and influence of changing system parameters such as type of faults like single line to ground fault, three phase to ground fault and double line to ground fault, also fault resistance and fault location; were taken the results show that the module respond in a very high speed relay, the performance of this distance relay is fast and accurate as compared with other relays the detection is with in less than 1⁄8 of the period.
