Aligned with this perspective, this paper proposes a novel topology of a multilevel bidirectional and symmetrical (MBS) split-pi dc-dc converter. As a central distinguishing feature, it operates with three voltage levels in both dc sides (0, vdc/2, vdc), meaning that the voltage stress in each semiconductor is reduced when compared with the conventional split-pi converters, and it operates with controlled variables (voltage and current) based on the interleaved principle of operation, although it is not an interleaved split-pi converter. As demonstrated along the paper, the MBS split-pi converter can be controlled with current or voltage feedback in any of the dc interfaces, while the common dc-link voltage is controlled by the dc interface where the source is connected. The adopted current and voltage control schemes, as well as the pulse-width modulation, are presented and comprehensively explained. The validation is presented for the main operation modes, where it is possible to verify the claimed distinguishing features of the proposed MBS split-pi converter.","PeriodicalId":111104,"journal":{"name":"2020 IEEE 14th International Conference on Compatibility, Power Electronics and Power Engineering (CPE-POWERENG)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123746274","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}

For balancing out seasonal fluctuations, conversions into heat or gas in combination with seasonal storage are frequently discussed approaches. In context of an optimal conceptual synthesis of such systems, investigations regarding the operation and design require a large time period of at least one year. In order to solve such optimal control problems, an immense calculation time is required. This contribution presents a multistep approach which determines the optimal operation strategy in an iterative way and is capable of reducing the calculation effort. In the first step, a rough optimization incorporating a low modeling depth is performed. Especially in combination with a rough time discretization, dynamic short-term storage (e.g. electrical batteries) can become irrelevant from an optimization point of view. Therefore, the considered system can be virtually reduced by several state and control variables resulting in a significantly reduced computation time. In this contribution, a method to analyze optimal control problems with respect to this kind of system reduction is presented. Using the results of the first optimization, a second fine optimization is performed to solve the full optimal control problem. While in the first step, the dynamic programming is utilized to solve the optimal control problem in one instance, the second step uses the mixed integer linear programming to solve multiple short time periods of the optimal control problem in a sequential way.","PeriodicalId":111104,"journal":{"name":"2020 IEEE 14th International Conference on Compatibility, Power Electronics and Power Engineering (CPE-POWERENG)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116519550","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}

As such, the power production is shifting towards more distributed generation consisting of renewable energy sources whose fluctuating nature complicates the balancing of supply and demand. Demand response methods have been employed to smooth the power needs by shifting loads to when there is a surplus of production. In this paper, power smoothing of fluctuating loads using a flywheel storage system is investigated for a small grid connected microgrid. A model of a low speed flywheel system is developed with a current control of the grid-side converter and field-oriented control of the motor-side converter. A moving average filter is used for power smoothing in a small microgrid. The performance of power smoothing could be adjusted by varying the length of the time window of moving average filter. An 81.9 % reduction in RMSE of grid power fluctuations was accomplished showing that flywheel storage can be successfully used to smoothen microgrid power.","PeriodicalId":111104,"journal":{"name":"2020 IEEE 14th International Conference on Compatibility, Power Electronics and Power Engineering (CPE-POWERENG)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122050341","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}

During charging and discharging processes the state of charge (SoC) of an ESS changes. Microgrid control, often based on droop curves, enables intelligent power distribution as well as voltage restoration in multi-infeed topologies and is necessary for taking care of the occurring SoC deviations. This paper compares different SoC control strategies based on droop control. An adaptive state of charge control has been developed using a proportional controller parameter (PCP) for shifting the droop curve on the current axis. In a case study the adaptive SoC control is validated for a droop-controlled industrial DC-microgrid with an ESS used for peak shaving. The performance of the adaptive SoC control is evaluated using quality criteria, e.g. peak load reduction, cut-off frequency and settling time. It is shown that the state of charge can be successfully kept within the desired range over time.","PeriodicalId":111104,"journal":{"name":"2020 IEEE 14th International Conference on Compatibility, Power Electronics and Power Engineering (CPE-POWERENG)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124232343","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}
