A novel application of an adaptive Proportional plus Integral (PI) controller with the purpose of improving the microgrid performance is presented in this paper. The control strategy of the adaptive PI controller is based on Widrow-Hoff adaptation technique. The efficiency of the suggested controller is proved by comparing its outcomes with that obtained by utilizing Flower Pollination algorithm (FPA) which is used to fine tune the PI controller parameters of the inverter based microgrid. The utilized multi-objective optimization problem used by the FPA is created by the Response Surface Methodology (RSM). Simulation results are carried out using PSCAD/EMTDC environment to check the validity of the proposed control strategy. The simulation results are tested under various operating states such as 1) conversion of the system from grid connected to stand alone mode of operation, 2) subjecting the system to three line to ground fault in the autonomous mode, and 3) exposing the system to the load variability in the islanded mode.","PeriodicalId":37583,"journal":{"name":"International Journal on Energy Conversion","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43105116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Perturb & Observe (P&O) and Incremental Conductance (INC) that are the most commonly used maximum power point tracking (MPPT) methods due to their simple structure and facility to implement. However, both have the limitation in the effective tracking of maximum power point under unpredictable and fluctuating nature of wind turbine systems. In order to overcome the above limitations a model predictive control technique is proposed in order to enhance energy efficiency of wind turbine systems during rapidly changing wind conditions. MPC is an optimization method, it offers fast tracking, low power oscillations in steady state as encountered with the conventional methods. The proposed method uses variable predictive perturbation step size determined by Newton-Raphson method. Compared to traditional P&O and INC, the proposed strategy converges to maximum power point more rapidly and reduces the steady state power oscillations around maximum power point (MPP). The effectiveness of the control scheme is validated using MATLAB/SIMULINK simulation studies and through a scaled laboratory model using dSPACE DS1007 platform in order to verify the simulation results.","PeriodicalId":37583,"journal":{"name":"International Journal on Energy Conversion","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43841533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The photovoltaic mathematical models depict a nonlinear I-V characteristic covering unknown parameters due to the restricted information given by PV panel’s manufacturers of the photolytic panels. This paper investigates the use of Water Cycle Algorithm (WCA); it will be the using world rivers/streams cycles. This accurate observing is a new population-based meta-heuristic optimizer. Here, WCA is simulated in MATLAB environment and applied to both single-diode model (S.D.M) and double-diode model (D.D.M) as represented. Authenticity of these proposed photovoltaic systems a model is ascertained by the simulations of the outcomes, where these simulations are implemented under different environmental conditions. Outcomes are compared to experimental results by Kyocera KC200GT PV module. The effectiveness and efficiency of proposed mathematical models are established through comparing models absolute error with respect to experimental outcomes and that of other photovoltaic systems models. The WCA can therefore be used, based on its results in developing accurate PV models.","PeriodicalId":37583,"journal":{"name":"International Journal on Energy Conversion","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67292641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is a member of a family of devices and switched dynamic voltage stabilization converters that were developed to ensure minimal loss of excitation, voltage stabilization, energy efficient utilization, power quality enhancement and harmonic distortion reduction in AC distribution grid networks. A novel-dual action distributed FACTS based–switched power filter compensator (SPFC) scheme is developed for efficient utilization of wind energy under varying wind conditions and major load excursions. A dynamic multi-level error-driven decoupled time de-scaled multi regulation control strategy is used to guarantee better power quality performance in terms of voltage enhancement and stabilization of the AC buses, improvement of power factor, and harmonic distortion reduction. The proposed SPFC was controlled using an inter-coupled weighted modified proportional-integral-derivative (WM-PID) controller. Cuckoo search (CS) optimization algorithm is employed to get the PID controller gains in terms of variations and excursions in wind speed and dynamic load excursions to reflect the performance of the compensator scheme. The effectiveness of the proposed SPFC with the multi-level control strategy has been assessed by time-domain simulations in Matlab/Simulink environment. The results obtained show the robustness of the proposed topology.","PeriodicalId":37583,"journal":{"name":"International Journal on Energy Conversion","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47710274","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
