Among them, wind and solar photovoltaics stand out for their availability and cost of implementation, with the disadvantage of climate dependence, that can be solved by an energy storage system, such as a hydroelectric reservoir. However, large hydroelectric plants require high implementation costs and follow strict environmental regulations that make their execution hard. In this sense, hybrid microgeneration systems that use solar photovoltaic and hydro sources can reduce the costs and environmental impact of large projects and maintain their dispatchable characteristic, making them an attractive alternative. This work presents a microgrid topology with three converters to connect the hydro and PV sources in the grid. The proposed Hydro-PV system demonstrates a gain in generation when compared with the standard Hydro-PV system, in rainy periods. That’s maintains a power generation suitable for feeding the load without extra power, enabling operation in off-grid mode without the use of batteries.","PeriodicalId":386920,"journal":{"name":"2023 IEEE 14th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"11 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":"126402697","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 thermal runaway and thermal propagation characteristics of LFP batteries caused by heating under the condition of 100% SOC is studied. A flame ionization detector and a palladium-nickel alloy sensor were used to measure the concentration changes of THC, CO, CO2, O2 and hydrogen inside the energy storage system during the thermal runaway process. The test results showed that the cells close to the heat source will undergo thermal runaway first, followed by thermal propagation between the cells. If flammable gas generated when the cells undergo thermal runaway accumulates in the energy storage system, it is easy to cause the fire hazard. Reducing the concentration of flammable gases inside the energy storage system and improving the maximum operation temperature of insulating materials would help to prevent the risk of fire and explosion.","PeriodicalId":386920,"journal":{"name":"2023 IEEE 14th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"135 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":"121476653","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, due to the planarized structure of GaN chips and the complex finger electrodes on its surface, the GaN devices packaged in the form of double-sided cooling are rarely reported. For enhancing the heat dissipation performance of GaN devices, a new double-sided cooling method is proposed. In this work, we developed a composite buffer, namely copper-wire-spacer (CWS), with anisotropic electrical conductivity. The CWS could cover the GaN chip surface to connect the drain, source and gate pad while avoiding short circuit between them. The GaN chip was packaged between the CWS for pads interconnection and two direct-bond-copper (DBC) for heat dissipation. The proposed method was demonstrated by fabricating single-chip packages of a (650 V, 150 A) GaN HEMT. Silver sintering was used as attachment. The power loop inductance was measured as 3.83 nH. The RDS was measured as 11.2 mΩ.","PeriodicalId":386920,"journal":{"name":"2023 IEEE 14th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"484 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":"122894698","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 shared DC-link between emulator and 3LT2I realizes energy recycling, but introduces an extra zero-sequence loop. This loop deactivates conventional 3LT2I neutral-point balancing methods that generate common-mode voltage, bringing excessive current burden to common-mode choke. Therefore, a neutral-point voltage balancing method using an extra converter leg is proposed in this paper, which is implemented by controlling the DC-link as an LC-filtered converter. In this scheme, the pressure of common-mode choke can be relieved, and the behaviors of the extra bridge is fully decoupled from 3LT2I under test, ensuring isolation and accuracy of testing during emulation. Simulation and results further confirm the feasibility and effectiveness of proposed method.","PeriodicalId":386920,"journal":{"name":"2023 IEEE 14th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"56 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":"116134213","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}

It is found that mismatched body diodes, asymmetric power-net layout and uneven junction temperature for PSMs can increase crosstalk voltages, leading to higher cross-turn-ON risk. Then the proportion of overall and separate gate resistance is adjusted and additional SiC Schottky Barrier diodes (SBDs) are employed to suppress crosstalk voltages of PSMs due to these mismatches.

It is responsible for emulating the kinetic energy and static/dynamic properties of conventional synchronous generators to solve the stability problems due to decrease inertia in the systems with high levels of RES. This has been increasing in the distribution grids where is common the single-phase loads and the current unbalance, which causes stability problems as the intensified frequency oscillations and the frequency deviation in the system. The VSM control is common in converters present in the balance system. However, the VSM control implementation in converters present in the unbalanced system is not a straightforward task due as the unbalances intensify the power oscillations to cause the VSM to have abnormal behavior. Nevertheless, the frequency and voltage droops controls are commonly used in the converters present in the unbalanced system, but they are used as grid-following converters. Therefore, this paper proposes an auxiliary droop frequency and voltage control (AFV) scheme to integrate into a virtual synchronous machine (VSM-AFV) in order to improve a four-wire power system’s stability during an unbalanced system. This approach is based on droop frequency and voltage control, and its law control is obtained from a system’s active power and reactive power flow exchange equation. Changes in the active power of the VSM based on unbalances presented in the distribution grid are considered to show the performance of the VSM-AFV. Results show that the VSM-AFV controller presents lower ROCOF, steady-state errors in output reactive power, and output current of a four-leg three-phase voltage source converter (4-LVSC) when compared to the VSM approach.","PeriodicalId":386920,"journal":{"name":"2023 IEEE 14th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"31 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":"122834292","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}
