A multi objective JAYA algorithm has been suggested to optimally design the proposed 2DOF-IDD controller under different functional conditions. The performance of proposed 2DOF-IDD controller has been investigated through a standard comparative study over 2DOF-PID and 2DOF-PI control control approach for generation control of the proposed plant under study. The dynamic performance of suggested JAYA algorithm has been compared over flower pollination algorithm (FPA), cuckoo search algorithm (CSA) and genetic algorithm (GA). An improved objective function called integral of time multiplied by absolute error (ITAE) has been considered while optimizing parameters of proposed 2DOF-IDD controller. The proposed power system integrated with the wind power station is modeled with existing conventional system for improving overall rating of the system.

During PS condition, PV panel shows multiple peaks in power-voltage (P- V) and current-voltage (I-V) characteristics, making conventional Maximum Power Point Tracking (MPPT) algorithms like Perturb and observe (P&O) method, Incremental conductance (I&C) method etc., fails to extract maximum power. Optimization based techniques like Particle swarm optimization (PSO), Cuckoo Search (CS) and Maximum power point scanning (MPPS) methods etc., can perform an active monitoring of maximum power under PS condition. Since, optimization-based systems are complex and time-consuming, in this paper an improved MPPT is proposed for tracking maximum power under PS condition. The Proposed MPPT method does not require any computational burden, making it more compatible for real time with good tracking efficiency. The proposed MPPT is verified for 3S configuration with various shading patterns showed satisfactory results with excellent dynamic behaviour and very high tracking efficiency.","PeriodicalId":247843,"journal":{"name":"2020 International Conference on Computational Intelligence for Smart Power System and Sustainable Energy (CISPSSE)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123588317","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}

In this paper we have discussed about the core data analytics and the manual evaluation to capture the exact patterns from a real time versatile building energy consumption dataset which could be utilized in the implementation of an AI based smart predictor. With high dimensional data visualization and data analytics we were able to attain relatively lower mean absolute error i.e. a reduction of error up to 40.22% in the data pre-processing phase. We have mainly focused on the handling of the real time energy consumption data set and to trace out the energy supply or consumption breakdown conditions. From a publicly available data set, various data pre-processing criteria have taken and prepared the data-frame for the multivariate prediction model. After data pre-processing linear regression has been used to predict the energy consumption per carpet area and the prediction efficiency has been compared for each cases.
