This paper proposes a bidirectional modular multilevel resonant DC converter (BM-MRC).

Moreover, the submodules on the MV side can achieve zero voltage switching (ZVS), and the H-bridge on the low-voltage (LV) side can achieve zero current switching (ZCS) with the proposed control method.

The compensator is formed by cascading multiple direct AC/AC chopper controlled impedance sub-modules, which can realize the continuous change of equivalent reactance from inductive to capacitive. CCI does not require electrolytic capacitors, is small in size, and can realize single-stage conversion of power without intermediate links. Due to the compensator's modular design, it can be manufactured at low cost using traditional industrial-grade components, which also eases system maintenance. In addition, by rationally designing the internal parameters of the CCI, not only can the transmission capacity be improved, but also the function of line fault current limiting can be achieved.

The prerequisite for BES large-scale application in the grid is reasonable configuration of BES. In this work, we aim to solve the problem of insufficient rationality and economy of the existing BES configuration scheme by proposing an optimal configuration scheme for BES considering multiple market segment revenues and degradation cost. The scheme aims to maximize the net present value (NPV) of BES and constructs a dynamic combined revenue model for BES participation in multiple market segments. Additionally, the proposed scheme can correct the degradation rate by using the rain-flow counting algorithm (RCA) and add constraints to BES capacity. The simulation results show that the scheme can achieve the optimal economy of BES configuration and achieve the balance between revenue and degradation.","PeriodicalId":386920,"journal":{"name":"2023 IEEE 14th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"4 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":"117318967","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}

Fast and accurate state of health (SOH) estimation is crucial to ensure the reliable operation and timely maintenance of these devices. This work proposed multiple linear regression (MLR) models to estimate the SOH of battery applied in forklift load profile and compared the estimation accuracy between extracting features from complete discharging-charging voltage curves and only charging voltage curves. Two features were extracted from two kinds of voltage curves respectively firstly, and the third feature was then extracted from many-step voltage curves to improve the generalization performance. The MLR was used to build the relationship between SOH and features. Finally, root mean square error (RMSE) was employed to evaluate the model accuracy. Results show that the MLR can effectively estimate SOH based on the three features and the estimation accuracy is higher when extracting features from only charging voltage curves.","PeriodicalId":386920,"journal":{"name":"2023 IEEE 14th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"44 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":"126008997","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}

In addition, the use of cross-correlation algorithm can extract signal information at a specific frequency accurately and easily. The battery impedance is measured online by applying a duty cycle perturbation on the power converter. The low ripple of this converter is achieved by interleaving the currents of each phase.

The impedance model of VSGs is an essential indicator that can reveal small-signal instability violation mechanisms. However, the whole impedance model mixes the dynamics of all control loops, making it difficult to gain insights into how high active power transfer degrades low-frequency stability via active power control. To overcome this issue, this paper decomposes the entire impedance model into three parts that are dominated by the voltage and current control, the capacitor voltage dynamic, and the output current dynamic, respectively. By identifying the capacitor voltage and output current dynamics, the proposed decomposition method provides a clearer understanding of how high active power transfer degrades low-frequency stability. Specifically, the decomposed impedance model shows that the qq-axis low-frequency phase angles of the capacitor voltage and output current dynamic-induced impedance components start from 270° and 360°, respectively, leading to possible low-frequency instability issues under strong grid conditions.","PeriodicalId":386920,"journal":{"name":"2023 IEEE 14th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"78 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":"125029067","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}
