<span>Distributed generation (DG) is an essential attributor in smart grid to fulfill the uncontrollable increase in the demand for energy. Artificial intelligent optimization techniques are widely used within automation systems for guarantee the optimal operation and utilization of DG allocation on the day-ahead power scheduling. In this paper, the genetic algorithm technique used for obtaining the optimal utilization of the automated operation of distributed generation for power losses and total cost minimization as well as user comfort maximization considering all operating constraints technique. Distributed generation represented by fuel cells to supply part of the daily demand in the power system. The target is to apply decision-making strategy of smart operation for economical and reliable operation of power system. Concentrated fuel cell units considered representing the available DG at the load centers. The methodology applied to the 11-bus test system. The simulation results have demonstrated that the GA capability for full automation of DGs in a smart manner within the power system for economic and safe operation</span>

Renewable Energy Generation

With the rapid development of distributed generation technology,a lot of renewable wind and solar power connect to the power system. Due to the random and intermittent characteristics of renewable energy, it brings a big challenge to the security and economical operation of power system. With the limits of climbing speed, non-renewable energy generation units cannot respond quickly to the change in the output of renewable energy generation units. Owing to the advantages of high luminous efficiency and long lifetime, LED lamps get rapid promotion and application in the smart distribution network. Based on the optical and electrical unique properties of LED lamps, the author studies the effects on the power system for a large number of LED lamps connecting to the distributed generation system, and establishing the mathematical model of LED lamp participating in the optimal dispatch of distributed generation system. In order to solve the model, the author uses gradient projection method. Through the SIMULINK simulation, it demonstrates that the algorithm has a fast convergence speed and high precision, and verifies the correctness and feasibility of the algorithm.

Distributed Generation (DG) plays a major role in existing power system. When such distributed generation system is interconnected with micro-grid improves voltage profile, power quality but at the same time results in fault conditions. Among various faults occurring in the power system, short circuit faults are the most predominant case. This results in the increase in flow of the fault current in the line. Also the equipments installed in such a line get damaged internally due to flow of excess fault current. Therefore in order to improve the transient conditions and limit the fault current to a manageable level, a device called Fault Current Limiters (FCLs) are being used in recent trend. This paper reviews about various fault current limiters, their development, characteristics and operating performance in the system. It gives a detailed knowledge about various operations performed by fault current limiters that is compared with other conventional techniques.
