A single stage Solar Photovoltaic (SPV) system is implemented for maintaining the DC link voltage (Vdc) of the Shunt Active Power Filter (SAPF). The system proposed, improves the Power Quality (PQ) of the utility system as well as feeds the solar energy extracted into the system. Maximum Power Point Tracking (MPPT) is implemented to excerpt solar energy. The purpose of the proposed system is to mitigate harmonics and neutral current (Isn),to compensate reactive power and to maintain power factor near unity. The SAPF improves the PQ of the proposed system. The control algorithm proposed for SAPF is Neural Network (NN) based Improved Linear Sinusoidal Tracer (ILST) algorithm. An instantaneous compensation technique controls the variations in PV power of the SPV system with fast dynamic response. The proposed system is also compared with battery operated Boost Converter (BC) SPV fed SAPF system. The battery operated SPV system boost the DC link voltage and thus improves PQ throughout the day. The NN based control strategy and the SPV system are modeled, developed and validated in MATLAB SIMULINK.

In general the transient stability is improved by increasing the excitation rapidly, by this method either the voltage regulation will be achieved or the transient stability could be improved. To improve both the transient stability and voltage regulation of power system simultaneously a composite controller (excitation and governor control) based on direct feedback linearization (DFL) technique is considered in this paper. It is proposed to compute the controller parameters by particle swarm optimization (PSO) technique, a heuristic optimization method. The complete procedure has been explained by an example of a single machine infinite bus system.

Different shapes of the tanks are utilised in the process industries according to the application. For high viscous fluids and complete drain is required the conical bottom tanks are prefered. But the nonlinearity due to the tapered bottom area of the tank makes the level control in the conical tank the toughest task. The conventional controllers will not gives a clear solution for this case. This work deals with development of a suitable controller for such process.

The battery SOC acts like an indicator of the internal charge level of the battery, in order to avoid unpredicted system interruption and prevent the batteries from being over-charged or over-discharged. SOC estimation procedure is one of the most complex techniques caused by complex battery chemistry and its strong non linearity. In this paper we have chosen a Kalman filtering algorithm to estimate internal states of Lithium Ion battery and dynamically estimate the SOC by decreasing divergence due to parametric uncertainty of battery model, measurement and process noise by using an Unscented variant of this filter. To further enhance the UKF algorithm, an adaptive calculation of noise covariance is proposed to combine between a better convergence and robust results. Experimental results indicate that the adaptive unscented Kalman filter based algorithm has better performance Battery State of Charge estimation. A comparison with other estimations techniques shows that the proposed SOC estimation method is the best choice in term of accuracy and robustness.","PeriodicalId":38433,"journal":{"name":"International Review of Automatic Control","volume":"10 1","pages":"349-358"},"PeriodicalIF":0.0,"publicationDate":"2017-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43296778","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}
