This scheme leverages the photovoltaic (PV) sources’ flexible power reserve ability to restore frequency during sudden imbalances in power demand-supply, while minimizing the size of the required energy storage systems. Application of PV power reserve in a distributed PEDG network comprising of sources with various capacities, reserves and other constraints has not been investigated so far. The proposed scheme accommodates these uncertainties in the estimation of the required active power $(Delta P)$. Moreover, the PAO module optimally allocates the estimated $Deltamathbf{P}$ demand among all the sources in the cluster, based on the available power reserves while also minimizing losses. In response, the power electronics converters/inverters in the PEDG adjust their power levels and support the network in restoring the frequency in a timely and cost-effective manner. The PAO module eliminates the droopbased coordination requirement and their associated drawbacks. Case studies illustrate the superiority of the proposed scheme over the conventional droop-based frequency restoration approaches.","PeriodicalId":64562,"journal":{"name":"智能电网与可再生能源(英文)","volume":"14 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2022-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81356900","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 proposed control scheme leverages model predictive control framework for enhanced active and reactive power sharing towards robust V/f regulation. The traditional PI-based V/f regulation for network of grid-forming inverters requires substantial tuning effort due to the nested loop control architecture. Furthermore, the PIbased V/f regulation for network of grid-forming inverters may not guarantee optimal active and reactive power sharing under different operation condition which could jeopardize the resilient operation of the next generation power grid. This paper is aiming to tackle this challenge by mitigating the required tuning effort and enhanced active and reactive power sharing for grid-forming inverters in a microgrid. Comprehensive analysis is conducted to show that the proposed approach can achieve good dynamic performance with negligible power ripple, in addition to an accurate active and reactive power sharing. The provided experimental case studies validates the theoretical expectation and effectiveness of the proposed approach.","PeriodicalId":64562,"journal":{"name":"智能电网与可再生能源(英文)","volume":"349 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2022-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86800058","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}

Typically, any related distortion can reflect several forms of negative impacts that might affect the system equipment operation. Power electronics-based apparatus within telecommunication data center facilities are generating such harmonic distortion causing well-known several power quality issues. Furthermore, such harmonics can also propagate back to the electrical grid increasing the risk of sensitive equipment failure and maloperation. In this paper, real measurement results of current and voltage waveforms along with their total harmonic distortion (THD%) investigations of typical telecom data centers are presented. In addition, a capacitor-less distribution static synchronous compensator (D-STATCOM) is proposed to improve the degraded levels of power quality indices. Simulation results using MATLAB/Simulink are presented in this paper confirming the effectiveness of the capacitor-less D-STATCOM device in providing dynamic compensation regarding power factor correction and harmonic distortion reduction.","PeriodicalId":64562,"journal":{"name":"智能电网与可再生能源(英文)","volume":"93 20 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2022-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90727666","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}
