Basic control methodology is to de-couple PQ control for grid-forming distributed generator (DG) whose new extra role is to act as reactive power sensor besides generating real power into the microgrid. Reactive power from the grid-forming DG is transferred to and from the instantaneous var compensator when there is a switch-in or switch-off of inductive load. By doing so, accurate control of real power becomes feasible so long its reactive power output is kept at low value. Generations of real power reference of both grid-forming and grid-supporting DGs are based on voltage variation at their terminals, so they don't need instruction from energy management center and are de-centralized. A multiplying factor is introduced to expedite such real-time real power reference generation to cope with fast switch-in and switch-off of large loads. Each of grid-forming and grid-feeding DGs performs within their respective generation capability. The system steady-state voltages can be maintained almost at rated value. The system operates at constant 50Hz. The proposed method is validated using real-time modeling in SIMULINK.","PeriodicalId":403316,"journal":{"name":"2016 IEEE 2nd Annual Southern Power Electronics Conference (SPEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128011200","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}

A simple single-bit ADC system i.e., Single-Bit Modulator (SBM) is considered as an alternative to the commonly used multi-bit ADC systems. Unique features of employing SBM are 1) its ability to convert analog signals into single-bit signals and 2) its easy integrability in digital chips with linear variable differential transformers (LVDTs) such as FPGAs. A SBM based PI (SBM-PI) controller is designed which guarantees consumption of less hardware resources, latency and effectively regulates the output voltage to provide the desired power transfer efficiency. The performance of the proposed SBM-PI controller is compared to that of a conventional multi-bit PI controller and has been shown that both controllers give identical performance. However, the SBM-PI consumes significantly less hardware resources. The effectiveness of the proposed controller with SBM-PI is further demonstrated using the experimental prototype of CPT using 16 MHz ATmega8 microcontroller. The experimental results from a laboratory prototype illustrate that SBM-PI controller successfully regulates the output voltage of CPT to control the power flow.","PeriodicalId":403316,"journal":{"name":"2016 IEEE 2nd Annual Southern Power Electronics Conference (SPEC)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115732904","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}

However, to realize a reliable and high-precision harmonic compensation system, current control and dynamic coordination strategy need to be optimized. In this paper, centralized current loop is optimized with amplitude and phase correction based on comprehensive analysis of the single PI current loop and selective harmonic detection under multiple rotating reference frame. An improved current-limiting strategy with harmonic frequency priority setting is proposed, which will improve the operation reliability and compensation capacity utilization. In addition, based on the proposed harmonic current control and current-limiting strategy, this paper presents dynamic coordination strategy for large-capacity harmonic compensation system. The proposed strategy determines operating mode according to the component of harmonic current. A novel parallel topology for modular active power filter combining two traditional topologies is used. Finally, the simulation waveforms and experiment results verify the reasonability of the proposed topology and control strategy.","PeriodicalId":403316,"journal":{"name":"2016 IEEE 2nd Annual Southern Power Electronics Conference (SPEC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115255781","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}

For instance, PV systems are currently required to remain connected under grid voltage sags (even zero voltage condition). In this case, much attention should be paid to the grid synchronization in such a way to properly ride-through grid faults. Thus, in this paper, the most commonly-used and recently-developed Phase Locked Loop (PLL) synchronization methods have been evaluated for single-phase grid-connected PV systems in the case of Zero-Voltage Ride-Through (ZVRT) operation. The performances of the prior-art PLL methods in response to zero voltage faults in terms of detection precision and dynamic response are assessed in this paper. Simulation results show that the Enhanced PLL (EPLL) and the Second Order Generalized Integrator based PLL (SOGI-PLL) are the most applicable to single-phase PV systems for ZVRT operation.","PeriodicalId":403316,"journal":{"name":"2016 IEEE 2nd Annual Southern Power Electronics Conference (SPEC)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123205043","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}
