This research focus on the problem that the energy storage side is often regarded as an ideal power supply when selecting the control parameters of conventional VSG, which makes the obtained parameters mismatch with the energy storage battery. Therefore, a fuzzy adaptive control strategy of the VSG system considering constraints of the discharging characteristics of energy storage battery is laid down. This tactic takes the state of charge (SOC) with operating power constraints of energy storage battery into consideration, so that the whole system can always maintain safe and stable operation when the grid is subject to arbitrary fluctuations. Using a fuzzy controller to change the virtual rotating inertia and damping coefficient instantly to realize adaptive VSG control. Using the energy storage SOC along with its capacity constraints to narrow the inertia value range so as to improve the frequency stability of the electrified wire netting. Finally, by comparing the frequency modulation response of energy storage converter under two modes of VSG control in the simulation environment of Matlab/Simulink, this paper proved the feasibility of the proposed VSG control policy.","PeriodicalId":227496,"journal":{"name":"2022 3rd International Conference on Advanced Electrical and Energy Systems (AEES)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125894445","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}

At present, the traditional vector control and direct torque control are difficult to meet the high-performance control objectives. As an advanced control strategy, model predictive control (MPC) is easy to realize optimal control. Model predictive current control eliminates the integral influence of current proportional integral controller and improves the dynamic response effect of current. However, its speed outer loop generally still adopts speed proportional integral controller, resulting in the unsatisfactory dynamic effect of motor speed. At present, most of the research on MPC of PMSM is carried out for a certain link of the control system, and the advantages of MPC performance are not given full play. Therefore, this paper applies the MPC strategy to the current control and speed control of PMSM for industrial robots to improve the dynamic and static performance of the system.","PeriodicalId":227496,"journal":{"name":"2022 3rd International Conference on Advanced Electrical and Energy Systems (AEES)","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116166851","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 object of study is the city of Valparaiso in Chile, because it is an example of electrified public transport.

Methodologically, the study will be carried out through the analysis of secondary sources with an urban historical approach of the city, focusing mainly on the means of transport and their influence on the development of the city, in addition to a specific study, both constructive and functional, of the elevators, to understand them and thus establish their sustainable role in the development of the city.

Ion current will increase the space charge density and affect the spatial electric field distribution on the roof, thereby affecting the insulation performance outside the roof, which may cause insulation flashover accidents. In this paper, according to the distribution of ion flow field near the 27.5 kV contact line of high-speed railway, the distribution characteristics of ion flow field around the contact line under the influence of different airflow velocities are analyzed by finite element simulation. The research shows that the electric field intensity around the contact line changes with the increase of airflow velocity, and the peak value of the roof synthetic field intensity decreases under the influence of airflow. Under the influence of high-speed airflow, the distribution range of spatial ion flow density is obviously biased towards the windward side, and the ion flow distribution is concentrated in the upper space of the roof, resulting in an increase in the distribution range of ion flow in the contact line-top space. The research results can provide a scientific basis for the optimization of roof external insulation design and the analysis of roof electromagnetic interference.","PeriodicalId":227496,"journal":{"name":"2022 3rd International Conference on Advanced Electrical and Energy Systems (AEES)","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121447022","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 leads to the inability to reduce building energy consumption through effective means during the construction stage of nearly zero energy public buildings, resulting in unnecessary energy waste. Therefore, it is far-reaching significance to study the influence of various factors on the energy consumption of public buildings. In this paper, 9 influencing factors are selected to study the influence of each factor on the energy consumption of public buildings by designing an orthogonal test table and establishing a typical building model in DeST. The conclusions are as follows: in the process of realizing nearly zero energy of public buildings in cold and arid regions of northwest China, the roof heat transfer coefficient and exterior wall heat transfer coefficient should reduce as much as possible within the scope prescribed by the Technical Standard for Nearly Zero Energy Buildings. In severe cold and cold region, high ventilation times and building orientation of 15° west of due north should be set. As for ground heat transfer coefficient, exterior window heat transfer coefficient, east west window wall ratio, for the two types of regions, they should be set in the middle of the level factor. Further, for severe cold region, north window wall ratio, south window wall ratio and building orientation should be set to 0.2, 0.4, and due north respectively.","PeriodicalId":227496,"journal":{"name":"2022 3rd International Conference on Advanced Electrical and Energy Systems (AEES)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114841741","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}

Then, the mapping of the coal mine underground substation in the virtual space was established to digitally express the physical model of the substation and the equipment operation logic in the virtual scene. Finally, relying on VR technology, the interaction capability between the system and the user is improved, and several functions such as roaming inspection, data analysis, and analog diagnosis in the substation are realized.
