Its thermal stress has an important effect on the reliability of the MMC system. Under normal operations, significant temperature distributions exist in capacitors among different submodules (SMs) of one MMC arm due to the capacitance variations. However, existing research mainly focuses on the thermal balance of power semiconductors, but less on capacitors. To solve this problem, this paper first reveals the relationship between the capacitor parameter distribution and the thermal stress distribution. Then a method for realizing the temperature balance of capacitors by controlling the equivalent modulation indexes of SMs with compensation voltage is proposed. The hot-spot temperatures of capacitors in an arm can be balanced to the average value, which relieves the thermal stress. The simulation analyses with the proposed method are conducted with the professional tool PLECS. Experimental results on a mission profile emulator for MMC capacitors also validate the effectiveness of the proposed method.","PeriodicalId":276307,"journal":{"name":"2022 IEEE 13th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115276086","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}

This paper proposes a method for controlling the single phase MMC connected to the grid by using one DC voltage source instead of two. In the proposed topology, the grid is connected in parallel with the lower arm, thus, creating a power mismatch between the upper and lower arms. The proposed control method injects a DC circulating current for the power transfer between the DC and AC sides and a fundamental frequency harmonic that is able to balance the capacitor voltages of the upper and lower arms under unbalanced arm power conditions. This method ensures the stability of the MMC operation and the grid while reducing the number of the employed DC voltage sources. The efficiency of the proposed method is revealed by simulations conducted on a single phase MMC connected to a low voltage grid using MATLAB/SIMULINK.","PeriodicalId":276307,"journal":{"name":"2022 IEEE 13th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124469157","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}

Existing communications infrastructure for information exchange are centralized at the distribution management system, with very little autonomy or intelligence at the grid-edge. As a first step towards achieving grid-edge self-healing, this paper aims to bridge this shortcoming by implementing a centrally coordinated rules-based FLISR scheme and integrating it with Open Field Message Bus (OpenFMB), which is a flexible publish-subscribe architecture with the potential to enable point-to-multipoint communications and is more robust and resilient to natural and man-made adverse conditions. A proof of concept is developed to validate the centrally coordinated FLISR and OpenFMB mounted on an SEL-3360 computer that interacts with a simple feeder network of five SEL-651R relays, an SEL-3530 RTAC, and a hardware-in-the-loop testbed. Results demonstrate the efficacy of this approach in enabling direct, low-latency information exchange. OpenFMB’s publish-subscribe data model also opens new ways to enable grid-edge interoperability among devices of different vendors interacting with different protocols.","PeriodicalId":276307,"journal":{"name":"2022 IEEE 13th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124810362","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 control structure is composed of two layers. The primary control level coordinates the output current of the Distributed Energy Resources (DERs) by utilizing the V-I droop control strategy. In this method, all DERs are synchronized to a common rotating reference frame. To realize proportional load sharing among the DERs, for each DER, the d and q components of the output voltage are determined in accordance to droop characteristics of the d and q axis currents. To eliminate the load sharing caused by the line voltage drops, the slope of the droop characteristic of each DER is altered by means of a distributed secondary control scheme. The secondary controller utilizes an event-triggered communication strategy, which remarkably decreases the exchanged data and saves bandwidth. Simulation results show that the proposed method favors smooth dynamic performance and efficient network utilization.","PeriodicalId":276307,"journal":{"name":"2022 IEEE 13th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123575386","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, before these converters are integrated into the existing grid infrastructure in large numbers, their impact on the overall system stability must be ensured by means of suitable test procedures. Given the risk, cost and complexity of field testing, an alternative promising approach to develop and test such power electronic components in a close-to-reality environment is Power-Hardware-in-the-Loop (PHiL). However, guaranteeing the stability and accuracy when coupling physical and virtual systems in a PHiL setup is still a major challenge. More specifically, a large part of that challenge lies in the interface between both system parts. To analyze the stability of the resulting PHiL system, this paper utilizes the Nyquist and the impedance-based stability criterion. In doing so, this paper shows that instabilities may result for higher frequency ranges where the AC network emulation has higher deviations to the respective theoretical model due to the implemented interface algorithms. These instabilities can be addressed by corresponding filter configurations. Furthermore, it shows that for three phase applications all impedance sequence components must be considered for stability analysis","PeriodicalId":276307,"journal":{"name":"2022 IEEE 13th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121889761","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 this paper, improvements to the resiliency of a distribution system are demonstrated using a multi-site evaluation environment consisting of a real-time Hardware-in-Loop (HIL) setup in which DERs and other IEDs are modeled; and an ADMS which monitors and is able to control the distribution system assets. The HIL model and the ADMS are located 2400 km away, with communication between the sites enabled by a data manager using Distributed Network Protocol 3 (DNP3), demonstrating the system’s capabilities even over long distances. After a simulated transmission system failure in the HIL demonstration setup, DERs and other devices are operated to restore critical loads and node voltage profile (to within the ‘nominal ±5%’ band) in the distribution system.","PeriodicalId":276307,"journal":{"name":"2022 IEEE 13th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122076260","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}
