For grid-connected inverters, there are two basic control modes: current source mode (CSM) and voltage source mode (VSM), also known as grid-following control and grid-forming control. Existing studies show that the CSM-controlled grid-connected inverters can operate stably under the strong grid, while the system stability margin decreases or even becomes unstable under the weak grid. The VSM-controlled grid-connected inverters are just the opposite. Some literature proposes a hybrid-mode control for the multi-inverter system under weak grids: the system contains both CSM-controlled grid-connected inverters and VSM-controlled grid-connected inverters, thus effectively improving the overall stability of the system. However, the existing literature does not quantify the capacity of the VSM-controlled grid-connected inverters in this system. Therefore, a stability analysis based on multi-performance-index constraints, such as stability margin and control bandwidth, is conducted for this hybrid-mode controlled system, and the optimal capacity configuration of VSM-controlled grid-connected inverters is obtained in this paper. Finally, the experimental results prove the correctness of the analysis.","PeriodicalId":289566,"journal":{"name":"2021 IEEE Industry Applications Society Annual Meeting (IAS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125799547","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}

Three PWM waveforms including high-frequency signals, middle-frequency signals, and low-frequency signals are utilized to generate desired PWM waveforms in order to attain the efficient step-down voltage gain of the buck converter. The three PWM waveforms are integrated into the single PWM control signal in which there exists multiple switching pulses in the power switch to result in eleven operating modes for the proposed converter. The small-signal analysis is also considered in the proposed converter by including the switched circuit model. Based on the volt–second balance condition, the proposed scheme is capable of generating the voltage conversion ratio which can be represented as the cubic function of the duty cycle if the duty cycles of the three designed PWM waveforms are the same under the continuous conduction mode. The proposed converter appears effective in cost since there is no need to modify the circuit in the traditional buck converter. Finally, the numerical simulations and the hardware experiments are conducted to verify the proposed scheme.","PeriodicalId":289566,"journal":{"name":"2021 IEEE Industry Applications Society Annual Meeting (IAS)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124775559","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}

A cluster of controllable load and generations (CLGs) is referred to as VB, and it operates similarly as the battery storage that reduces the size of the energy storage device (ESS). Aggregators use the VB to distribute power among CLGs when the grid has excess or shortage capacity. The management of a microgrid with renewable energy instability and VB is a difficult problem; as a result, this proposed study introduces adaptive robust optimization (ARO) for unit commitment (UC) problems in microgrids that takes VB into account. Three separate UC cases are depicted in the proposed scheme. Case 1 treats only optimization and deterministic UC problem for the day ahead forecasted load; Case 2 discloses the UC with treating robust optimization, which considers forested reference day ahead load utilizing robust constraints. Case 3 emphasizes real-time load considering the worst uncertainty/prediction error of renewables and virtual battery for polishing the actual load. A neural network is adopted to forecast variable renewable generations (VRGs) output power. MATLAB® simulation with Mixed Integer Linear Programming (MILP) has been utilized for solving the ARO UC problem with VB.","PeriodicalId":289566,"journal":{"name":"2021 IEEE Industry Applications Society Annual Meeting (IAS)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126506327","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 steps must be taken to prevent security issues including ground fault currents and leakage currents, which can be prevented by connecting the PV panel to the ground through a parasitic capacitor. The proposal for new topologies with their control techniques and the modulation schemes have been inspired by the reduction of leakage currents issues. In this paper, improved topologies of single-phase transformerless inverter are proposed to reduce the leakage current and total harmonic distortion (THD) of grid current. These new topologies are named as H9 and H10 inverters according to the number of the switching devices in the inverter. Pulse width modulation (PWM) method is used for the inverters to suppress harmonics at the output grid current. The proposed H9 and H10 topologies can reduce the THD to 1.62% and 2.09%, respectively, at the grid current. The proposed topologies are extensively tested using simulation and test outcomes are presented.","PeriodicalId":289566,"journal":{"name":"2021 IEEE Industry Applications Society Annual Meeting (IAS)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121343893","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}
