In this paper, a structure-integrated partially-isolated three-port converter is proposed. This converter has compact structure, flexible power transfer path, and the different power transfer modes can be implemented by the developed phase-shifted PWM modulation strategy. Meanwhile, the proposed converter features high voltage gain, exhibits simple parameter design, avoids voltage spikes caused by leakage inductance, and achieves zero-voltage switching (ZVS) of all switches, which makes it more practical and attractive in practical applications. The topology derivation, power transfer modes, operation principle and parameter design are thoroughly analyzed. Finally, a simulation model is built and tested on PSIM 9.1, and the simulation results validate the effectiveness and correctness of the proposed partially-isolated three-port converter.","PeriodicalId":386920,"journal":{"name":"2023 IEEE 14th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"254 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121152392","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 output power characteristics of BESS when providing FM services are important for the state of health of battery. However, the current studies mainly focus on BESS output characteristic at smaller timescale when providing FM service to power grid, and the long-term analysis is lacked. This paper focuses on the long-term output power characteristics of BESS when providing different FM services, where the real frequency data of the UK power grid is adopted for analysis. Firstly, the frequency is converted to load power increment based on the power-frequency relationship. Then, the control systems of BESS and frequency dynamic models for two different scenarios, i.e., primary FM (PFM) and primary & secondary frequency modulation (PFM&SFM) are developed. By inputting the transformed load increment data to the frequency dynamic model with FM services, the dynamics of grid frequency, active power of synchronous generator (SG), and output power of BESS are obtained. The BESS output power in different FM scenarios is compared, and the indexes of battery during FM are analyzed.","PeriodicalId":386920,"journal":{"name":"2023 IEEE 14th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124355136","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}

To practically implement this variant of SHE, the switching angles solved for at discrete values of the amplitude modulation index, across its full operating range, must be pre-computed off-line, and then stored within a look-up table on the digital controller. As a result of this off-line implementation, conventional SHE configured with amplitude modulation index control features poor dynamic performance and requires the use of a large, memory-exhaustive look-up table. This paper presents an on-line SHE scheme that models each of the necessary independent switching angles as polynomial functions of the amplitude modulation index using curve-fitting techniques. This method of implementation allows for the switching angles to be accurately recomputed in real-time, thus offering improved dynamic performance and eliminating the need for a large look-up table. Additionally, the inherent benefits of conventional SHE are retained. Experimental verification proving the effectiveness of the proposed on-line SHE scheme is provided.","PeriodicalId":386920,"journal":{"name":"2023 IEEE 14th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"88 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120888256","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}

Many coordination strategies have been proposed for HESS, but most of them rely on communication system. This paper proposes an enhanced dual virtual impedance droop strategy without communication for HESS. A high-pass filter-based virtual resistance droop control is used for battery converter to solve the issues of DC bus deviation state-of-charge (SoC) violation. An adjustable virtual impedance droop control applied to a SC converter can realize the constant current charge or discharge of the SC in the steady state to prevent the SC’s SoC from exceeding the critical value. With the proposed control strategy, SC’s SoC can be automatically recovery while considering boundary conditions, thus improving the service life. Moreover, the approach can realize the high and low frequency power sharing between the SC and the battery, and the bus voltage can be restored to the nominal value. Simulations are conducted to verify the effectiveness of the proposed control strategy.","PeriodicalId":386920,"journal":{"name":"2023 IEEE 14th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131675786","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}
