“…Moreover, the application of IHBV model in Ajichai basin with 19 parameters and with a calibration period of 3287 days, takes only 284 seconds for 3500 iterations. Although the computational time in these models is not too long, it is still possible to reduce it significantly using other state-of-the-art optimization methods such as Surrogate-Enhanced Evolutionary Annealing Simplex Algorithm (SEEAS) or Melody Search (MeS) algorithms [65,66].…”

Partitioning Scheme (PS) is one of the strategies that could play a constructive role in improving the performance of conceptual rainfall-runoff (CRR) models. The main objective of this paper is to develop a Rainfall Runoff-Partitioning Scheme (RR-PS) with the ability of distinguishing different flow regimes in a basin and simulating each regime separately. The model utilizes a combination of PS and "regular" procedures and is equipped with Fuzzy C-Means (FCM) and Seasonal Partitioning (SP) to recognize different flow regimes. In addition, to avoid excessive increase of the model parameters caused by PS, sensitivity analysis is used to recognize the sensitive parameters. The PS part of integrated model is only run for the "sensitive" parameters and the "regular" part of model is implemented for the "less-sensitive" parameters. Data from three different scale basins in USA and Iran are used to evaluate the models. A HBV-Light (Hydrologiska Byråns Vattenbalansavdelning-Light model) based CRR model (Improved HBV-IHBV) is developed in FORTRAN (Formula Translation) with several modifications for testing the procedures. The results show that in all cases IHBV-based models using PS method perform better than the regular IHBV model. Overall, IHBV-SP demonstrates better performance than the other PS based models. Further improvement is reached by adopting user-defined seasons in IHBV-SP through optimization.

“…Pitch adjustment band width ( BW ) and pitch adjustment rate ( PAR ) play a vital role in deciding the convergence speed of the algorithm (Figure D). The bandwidth and PAR are varied in an exponentially decreased manner and linearly increased manner, respectively . The necessary equations are as follows:

k_{i, d} = k_{i, d} + {rand}^{*} italicBW

k_{i, d} = k_{i, d} - {rand}^{*} italicBW

italicPAR ((), t) = italicPAR ((), t - 1) + ((), \frac{{italicPAR}_{\max} - {italicPAR}_{\min}}{G_{\max}}) * t

italicBW ((), t) = {BW}_{\max} + exp ((), \frac{log (\frac{{italicBW}_{\min}}{{italicBW}_{\max}})}{G_{\max}}) * t

where, t is the current number of iterations from maximum number of generations ( G max ).…”

Summary In this paper, optimized controller design for multiple distributed generators (DGs) based microgrid network is discussed, where IEEE 1547 standards are followed for primary photovoltaic DG. According to standards, the primary photovoltaic/auxiliary battery energy storage system is integrated through voltage source converter's feedback controller, with operational modes: active reactive (P − Q) power control for grid synchronized operation and voltage frequency (V‐f) droop control for islanded microgrid. To overcome the inadequacy of conventional controller tuning in a multiple DGs‐based weak microgrid architecture, a new mutation based improved firefly algorithm is proposed in this paper. The worst stability operation is considered for voltage source converter's P‐Q and V‐f coordination during insufficiency in battery energy storage system management. The effectiveness of the proposed technique is validated on MATLAB Editor/ Simulink platform. Further, a hardware‐in‐loop test bench validation is achieved by TMS320 C6713 based DSP Starter Kit and embedded MATLAB coder.

“…A case study taken from the literature has been investigated with the hybrid algorithm and the results have been compared with the findings of Quantum behaved Particle Swarm (QPSO) [40,41], Melody Search (MS) [42], Artificial Cooperative Search (ACS) [43], Backtracking Search (BS) [44], Bat algorithm (BAT) [45], Cuckoo Search (CS) [46], Intelligent Tuned Harmony Search (ITHS) [47] and literature studies. Comparisons reveal that TLBO-DE is superior to all compared algorithms in terms of solution accuracy and efficiency.…”

Simulation proton exchange membrane fuel cell (PEMFC) performance accurately is a challenging process. Many mathematical models have been existed, yet due to lack of accurate parameter estimations, considerable errors might occur. Nowadays, meta-heuristic optimization algorithms have been successfully applied for parameter identification of PEMFC models. In this study, Teaching Learning Based Optimization method (TLBO) is hybridized with Differential Evolution (DE) algorithm for successful estimation of unknown PEMFC model parameters. Efficiency of the proposed algorithm is tested with several benchmark problems.
