Optimal distribution capacitor planning is an important task for economic operation of power systems. The optimal distribution capacitor planning is a combinatorial optimization problem which considers both power losses and cost of capacitor installation subject to bus voltage constraints. Discrete nature of capacitors, different load are considered in the(More)
This paper focuses on unit sizing of stand-alone hybrid energy systems using bees algorithm. With different combination of renewable sources, two types of hybrid energy systems are taken as test systems. Apart from the non-conventional sources like wind turbines, solar panels along with micro hydro plant, the systems have been optimized with fuel cell,(More)
This paper introduces an Improved Artificial Bee Colony algorithm for modeling and managing Micro Grid (MG) connected system. IABC differs from ABC because of its inclusion of Gravitational search algorithm (GSA) in the scout bee phase. Hence, the scout bee phase is substantially improved as the gravitational constant of GSA increases searching accuracy. As(More)
The significance of interconnected power system is growing day-by-day as many a times the availability resources for electric power generation depends on geographical locations and is distributed in nature. At the same time the strengths of demands are not uniform in a country like India. Hence to mitigate the gap between power generation and demand,(More)
Laser beam machining is a thermal energy based non-contact type advanced material processing technique which can be applied for almost all materials. Nowadays there is an increasing trends towards miniaturization of various components used in different applications like MEMS, photonics, microelectronics, robotics, bio-medical devices, etc. which needs(More)
The concept of Distributed Generation (DG) emerged in the power industry from the last few decades due to the rapid increase in electricity demand, limited conventional resources and continuous growth in nonconventional energy based low voltage and small scale power industry. In distributed generation system, the optimal placement and sizing of DG units in(More)
Present work<sup>1</sup> presents the modeling and design of off-grid hybrid renewable energy system considering the degradation of the system components and equivalent reduction of emission from conventional systems. The test system considers the solar PV, wind, fuel cell, electrolyzer along with the micro-hydro plant. Initially the work concentrate on the(More)
Present paper discusses about a reliable and cost effective optimal design for hybrid energy systems using meta-heuristic techniques. Design, planning and control of hybrid systems require complex optimization of the same which may not be solved easily with the conventional optimization methods. Several meta-heuristic optimization techniques such as(More)
