Gbest-Artificial Bee Colony Algorithm to Solve Load Flow Problem

Abstract: Load flow problem has a great significance to analyze the power system network due to its roll in planning and operation of network. Generally, Newton–Raphson (NR) method is used to analyze the load flow problems due to its efficiency and accuracy. But, NR method has some inherent drawbacks like in-efficient for highly loaded network, assumption are required for initial values and abnormal operating conditions. To overcome the existing drawbacks of NR method, a recently developed swarm intelligence based algorithm, namely Gbest guided Artificial Bee Colony algorithm (GABC) is applied to solve the load flow problem for five bus network. The reported results of GABC are compared to the results of NR method and basic ABC algorithm, which show that the accuracy of unknown parameters such as voltage, angle and power produced by GABC is competitive method to the NR method and basic ABC algorithm based method.

Disruption operator-based spider monkey optimization algorithm

Abstract: Spider monkey optimization (SMO) algorithm, is a neoteric Swarm Intelligence based algorithm, inducemented from the social comportment of spider monkeys, commonly known as fission-fusion social system. Despite of perpetuating an equilibrium state betwixt intensification and diversification by its own, SMO sometimes converges at a particular point due to its swarming nature. To overcome this problem, a new stage, namely disruption stage is incorporated with SMO. The proffered variant is named as Disruption operator-based spider monkey optimization (DiSMO) algorithm. In the incorporated stage, the disruption operator helps to scatter the swarms in convergence condition and according to the difference from the best solution, this operator is employed to entire solutions so that the solutions might attract or distract from the best solution. Further, the efficiency of the proffered strategy is estimated over 12 different benchmark functions and the outputs are being compared with basic SMO, its significant variant: power law based local search in SMO (PLSMO), and particle swarm optimization (PSO).

Parabolic shape ground plane having T-slots directional UWB antenna for airborne radar system

Abstract: A novel design technique of parabolic shape ground plane directional ultra-wideband (UWB) with circular patch antenna for airborne radar system is being presented here. The feed for the proposed directional ultra-wideband antenna is given by microstrip line and T-slots are inserted diagonally at the corners of parabolic ground plane in order to increase the directivity. The simulation analysis of the antenna is done on software CST Microwave Studio using FR-4 substrate with dielectric constant 4.3. The simulated results have shown a good return loss with respect to −10 dB. The radiation pattern characteristics and surface current distributions of the antenna at different frequencies are also given.

Levelized Cost of Electricity with Degradation of 10 MW Grid-Connected Photovoltaic Power Plant in Kalwakurthy, India

Abstract: The Total Renewable energy share of India is 70 GW as till on June 2018, out of 70 GW power 21.8 GW comes from SPV plants which are grid connected. In this paper, the grid-connected Shining sun solar photovoltaic (SPV) plant, Kalwakurthy, Telangana having a capacity of 10 MW (AC) & 11.1 MW (DC) which is operation since November 2015 is studied and analyzed. This paper evaluates various parameter such as performance ratio, cumulative utilization factor of the array. These parameters are calculated using namely Excel sheet. The monthly performance ratio obtained from the practical data varies between a range of 82% - 89%. The plant site is evaluated by using the generation data from the January 2017 to December 2017. Levelized cost of energy (LCOE) has also been calculated for the plant during the year 2017. Apart from this, the plant is studied for the degradation of the module. Degradation analysis is important in photovoltaic(PV) modules to monitor the performance of the PV system. PV module degradation over the spine of time, for calculation of the results such as 0.2%, 0.4%, 0.6%, 0.8%, 1%, 1.2%, 1.4%, 1.6%, 1.8, 2% degradation is considered.
