The problems of circulating current and capacitor voltage balancing for the MMC have been widely studied in available literature but little work is done towards grid current control with fast dynamic response. Conventional current controllers use PI or PR controllers which are slow and thus degrade transient performance of the MMC. Recently reported Model Predictive Control (MPC) methods for MMC aim to control the grid current but MPC suffers from computational burden and difficulties in adjusting of weights. Space Vector based Hysteresis Current Controllers (SCHCC) have been well established for drive applications. In this work, an SVHCC has been developed for a grid connected MMC system. Simulation studies show fast current control for cases of sudden change of active power reference and current reference. The controller exhibits quick tracking of the current reference in all cases. The proposed method has been discussed for a MMC system with three submodules, but it may be extended to any number of submodules and can be easily implemented in a digital controller with less computational effort.","PeriodicalId":124226,"journal":{"name":"2020 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130081501","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}

Failing to address this problem renders the cascaded system prone to instability. This paper introduces three different parallel virtual impedances, connected across the capacitor of the source side converter for restoring the stability and also for improving the dynamic performance of the load converter, during the external disturbances. The specific advantage of the proposed approach is that it requires the sensing of voltage across the LC filter rather than the current through the inductor in LC filter for designing the required virtual impedance. All these impedance configurations not only provide stability but also ensure a good dynamic response both across the LC filter and at the load converter's output voltage terminals. The response from the MATLAB/SIMULINK based simulations reveal the stability at steady state and the dynamic performance shows the improvement over a second order virtual impedance and an optimal method. Among the chosen impedance network configurations, the series RL network exhibits superior dynamic response to external disturbances. Analytical and simulation results of the work are included.","PeriodicalId":124226,"journal":{"name":"2020 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES)","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130189856","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}

Proposed charger operates in discontinuous inductor current mode benefiting limited components for its operation and achieves natural power factor correction (PFC) at adjustable grid input supply. Also, grid input voltage and current sensing are not necessary making the charger cost effective, and rugged to high-frequency noise. Correspondingly, the control becomes simple with the use of one voltage sensor and requires only one control loop. Moreover, as the converters have fewer semiconductor devices the voltage stress on the devices is also reduced in comparison with traditional bridgeless topologies. This consequently reduces the switching losses in the semiconductor devices and meliorates gross efficiency. Furthermore, the presence of only one semiconductor device in the current flowing path over a switching cycle greatly reduces the conduction losses while also facilitates the eases of thermal management. A comprehensive steady-state analysis over one switching sequence and the design equation is presented. The proposed EV charger analysis and the design are confirmed with the simulation and experimental results which uphold the design of the proposed converter.","PeriodicalId":124226,"journal":{"name":"2020 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133893105","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, additional control along with a higher order phase-locked loop (PLL) must be integrated to SV control, for ripple free power injection into an unbalanced grid. Thus, the enhanced-PLL (EPLL) structure comprising of positive, negative and zero sequence core units, is integrated to standard SV control in the proposed control, which is capable of ripple free power injection by DER into an unbalanced grid. Further, the proposed integrated control is also capable of successfully achieving pre-synchronization i.e., synchronization of DER voltage to the grid voltage, before connection of DER to the grid. Other important benefits of proposed control over existing VSG methods for unbalance grid condition, are reduced number of parameters design due to the simple modular control structure and usage of inherent low pass filter of SV in the positive sequence core unit. Simulation results demonstrating successful pre-synchronization and ripple free power injection by DER into an unbalanced grid are presented in this work.","PeriodicalId":124226,"journal":{"name":"2020 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134380696","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 issues like heavy computational burden, tedious weights selection process and lack of fixed switching frequency seriously inhibit its application for large systems like the Modular Multilevel Converter (MMC). To tackle this problem, this article proposes a unique simplified two-stage MPC strategy for the Modular Multilevel Converter (MMC) using a simple search algorithm. The proposed technique falls under the category of Modulated MPC. One of the major advantages of this method includes fixed switching frequency for MMC with $2mathrm{N}+1$ levels in the phase voltage, which is absent in many other MPC techniques in literature. Moreover the circulating current suppression and the output current control are decoupled. The capacitor voltage balancing is carried out using the simple reduced switching frequency type of sorting. It has lower computational complexity and ensures simplified digital implementation. The simulation results carried out using PLECS for 10 SM/0.7 MW MMC connected to a passive load validate the performance of this proposed algorithm.","PeriodicalId":124226,"journal":{"name":"2020 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130734572","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}

Battery Energy Storage Systems (BESS) are attracted more popularity for the usage of ancillary services support due to its faster response. Since the deployment of various battery technologies are under the pilot stage and not take on large scale installations across the globe, the cost of the BESS is quite expensive. Also, these battery systems have restrictions of operation for a limited number of life cycles. Given the economic aspects and limited life cycle operations, it is essential to utilize the battery systems optimally, efficiently and cost-economically. In this paper, a new algorithm called Dynamic Frequency Regulation (DFR) is proposed which is based on the prediction and historical operating data along with live data profiles. It helps to enhance the life of the battery systems by ensuring the necessary requirements of ancillary services applications. The proposed algorithm simulated through MATLAB and the results are compared with real time Conventional Frequency Regulation (CFR) output of the Li ion battery integrated with the 22kV feeder located at Power grid Puducherry. The life of the battery system is enhanced by 80% more compared to the CFR methodology. Further, the proposed algorithm shall be implemented on real-time grid-connected LiFePO4 BESS of 500KW/250kWh capacity established by POWERGRID at Puducherry, India.","PeriodicalId":124226,"journal":{"name":"2020 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES)","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131107032","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}
