This paper analyzes the integration of two networks from two aspects: 5G network improves the operation performance of smart distribution network and smart distribution network contributes to the promotion and construction of 5G network. On this basis, the key elements of the integration of 5G network and smart distribution network are sorted out, including energy elements, information elements and resource elements, and the integration planning of smart distribution network integrating 5G network is proposed.

In this paper, we firstly define a series of features indicating the abnormal events on the data collected by the battery management system during EB discharging periods, then apply graph signal processing concepts to detect abnormal discharging events, contributing to further fault location, retrofit and life assessment on battery cells, etc. In the experiments, the proposed method is validated on thousands of discharging cycles collected in the real world under two evaluation metrics and outperforms two benchmarks based on fuzzy c-means and affinity propagation.","PeriodicalId":118112,"journal":{"name":"2022 7th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123781546","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}

First, the paper modeled coal-fired power plants with carbon capture, utilization and storage (CCUS) equipment, concentrating solar power (CSP) plants with thermal energy storage (TES) systems, wind power plants, photovoltaic power plants and battery energy storage systems (BESS) in the zero-carbon power system. In the coal-fired power plants with CCUS equipment, the constraints of electric power output and zero carbon emissions were considered; considering the time-series state of charge constraint, a model of the battery energy storage system was established; considering the SOC of the thermal energy storage system and power balance constraints, a CSP plant model was established. The sequential Monte Carlo simulation method is used to build the process framework of probabilistic economic and adequacy evaluation. The uncertainty of new energy sources and load, and the stochastic outage of components are all considered in the framework.

In order to study the surface discharge characteristics of C4F7N gas mixture under the needle-plane electrodes, a fluid model of surface discharge was established using COMSOL Multiphysics for simulation, and the change patterns of electric field and photon flux during the development of streamer were obtained. By obtaining the change law of photon flux, it can provide the theoretical discharge. The simulation results show that the development process of streamer can be divided into three phases: streamer generation phase, streamer deceleration phase and streamer acceleration phase. During the whole process, the change trend of photon flux is basically consistent with the change trend of electric field. In the acceleration phase, the streamer gradually moves away from the needle electrode, the background electric field gradually decreases, and the frequency generated by the electron collision reaction weakens, leading to the slow development of the streamer, and the electric field and the photon flux at streamer head gradually decrease. In the acceleration phase, the streamer is converted from parallel to the plane electrode to perpendicular to the plane electrode, and the potential gradient becomes larger, leading to a faster development of the streamer and a gradual increase of the electric field and photon flux at streamer head.","PeriodicalId":118112,"journal":{"name":"2022 7th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114581071","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}
