It ensures that the electricity supply is reliable and affordable to industrial and commercial customers. The critical issues are the asymmetric fault components on the high voltage side due to different dynamic loading scenarios among the customers. The gas circuit breaker selection must consider all the worst scenarios. This paper investigates a substation of 13SkV transmission and 13.2 kV distribution circuits. A procedure is proposed based on the steps required to plan and design a substation. Iteration was performed in different dynamic loading scenarios. The critical parameters like the maximum fault current, dc component, and peak asymmetrical fault current were found to select project-specific gas circuit breakers to ensure reliable and optimal power flow through the substation.","PeriodicalId":402897,"journal":{"name":"2022 IEEE International Conference on Power Systems and Electrical Technology (PSET)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123261643","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 a result, the inverse peak shaving characteristics and randomness of intermittent new energy have brought great difficulties to the peak shaving and frequency regulation of the power grid. To solve this problem brought by new energy, this paper proposes a novel peak shaving and frequency regulation coordinated optimization scheme for the multi-power system including wind power, solar power, thermal power, hydropower, battery energy storage, and pumped storage. In the proposed scheme, uncertainties of the intermittent energy generation and load demand are considered. Besides, the demandside management and hydropower are considered to participate in the peak shaving and frequency regulation with the goal of minimizing the net load fluctuation and power abandonment. Finally, simulation results carried out in the MATLAB environment show that the proposed scheme is feasible in maintaining the stable operation of the system and improving the consumption level of new energy.","PeriodicalId":402897,"journal":{"name":"2022 IEEE International Conference on Power Systems and Electrical Technology (PSET)","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125242083","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, high-order grid-connected inverter may bring resonance issue easily. To address this issue, this paper is dedicated to obtaining maximal damping ability for high-order grid-connected inverter via a solving-equation-based analysis method. Firstly, a discrete-domain expression of high-order grid-connected inverter is derived. Secondly, the damping characteristics based on the derived expression are analyzed in detail by combining multiple influence factors simultaneously. Furthermore, to obtain the largest damping ability, the maximal damping ratio (MDR) curve is also given in order to provide a guideline to design controller parameters in practice.

Based on this, this paper proposes an FRT strategy for GFM converters, which not only considers the hardware constraints (i.e., current constraints) of the converters, but also can keep GFM converters running in the protected mode under symmetric and asymmetric faults. Firstly, the FRT of GFM converter is analyzed in detail. Then, an appropriate FRT model and control method are established. Finally, the effectiveness of the proposed method is verified by power-hardware-in-the-loop (PHIL) simulation and experiment. The results show that compared with GFL, the proposed control method can guarantee the instantaneous injection of reactive current when the GFM converter fails to prevent the overcurrent problem. Finally, the GFM converter can still operate fault-tolerantly under severe fault conditions.","PeriodicalId":402897,"journal":{"name":"2022 IEEE International Conference on Power Systems and Electrical Technology (PSET)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131797196","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}

Therefore, typical substations in geographical position and voltage level were selected as the objects of research, and high frequency current PD detection method and digital oscilloscope were used to systematically study the characteristics of electromagnetic interference signal in the substation in time-domain, frequency-domain, and statistics by field testing. Moreover, the location of the interference signal source was performed. It is found that the periodic interference signal and the external discharge of HV equipment in substations are the main forms of electromagnetic interferences for PD detection. The large-amplitude electromagnetic interference signal existing at the station will adversely affect the partial discharge detection. Especially the pulse interference signal, whose time-frequency characteristic is similar to the partial discharge signal, it is very easy to cause misjudgment of the detection system.","PeriodicalId":402897,"journal":{"name":"2022 IEEE International Conference on Power Systems and Electrical Technology (PSET)","volume":"172 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116274313","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}
