To preserve the privacy of different energy systems and give full play to the role of the interconnected system in wind absorption, a decentralized economic dispatch strategy of integrated electricity-gas energy system (IEGES) considering power to gas $(mathrm{P}2mathrm{G})$ and line pack is proposed. Firstly, P2G is applied to realize the conversion of wind power to gas, and the operating cost of P2G is considered to avoid over-conversion of power from other sources. After that, the regulation mechanism of line pack is analyzed, so that it can cooperate with P2G to store wind power without additional cost. Then, the decentralized solution framework of IEGES is constructed based on the alternating direction method of multipliers (ADMM), and the day-ahead economic dispatch model of IEGES is established considering various operating costs and safety constraints. Moreover, the nonlinear model is processed by a linear AC power flow algorithm and an incremental linearization method to reduce the difficulty of solution. Finally, the effectiveness and economy of the proposed strategy are verified by simulation analysis.","PeriodicalId":339798,"journal":{"name":"2020 IEEE 4th Conference on Energy Internet and Energy System Integration (EI2)","volume":"32 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133204678","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, existing district cooling and heating systems are difficult to upgrade to Integrated Community Energy System (ICES) systems through large-scale renovation and equipment replacement. This article takes two adjacent energy stations in the Shanghai World Expo Central Business District as a case study and establishes a comprehensive optimization model of equipment based on the partial load performance characteristics of each piece of energy supply equipment Combined with the district’s hourly energy demand. It compares the energy efficiency of the two modes of energy supply for each station and their interconnected energy supply. The calculation results show that operating the two stations in an interconnected manner increased energy efficiency by 18.6% compared to the operation of each energy station alone. The result indicates that, through interconnection and mutual operation between energy stations, it can not only add more interruptible time for the transformation of energy stations but also help to improve the energy efficiency of energy stations.","PeriodicalId":339798,"journal":{"name":"2020 IEEE 4th Conference on Energy Internet and Energy System Integration (EI2)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127822478","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}

Simultaneously, the Fractional-order PID (P $I^{lambda}D^{mu}$ or FOPID) controller is a natural extension of the PID controller. In this study, the FOPID controller’s implementation is performed in an industrial distributed-control system used here to control a laboratory unit’s level. A user-defined function block in ABB-DCS software is built to make the FOPID controller implementation possible. In order to create this new function block, one of the FOPID controller discretization methods is first presented and used for getting the discrete form. A system response’s comparisons using FOPID and the conventional PID controller are accomplished via simulation (using a particle swarm optimization and genetic algorithms) and experimentally (using the experimental setup). This experimental setup consists of the controller (ABB-DCS AC 700F2), which is connected to a desktop computer via ethernet cable, and the plant (Lab-Volt Level-Process Station), which is connected to the analog module of the DCS. A relative development in system response is shown in the results using the advanced FOPID controller comparison with classical PID and traditional FOPID controllers.","PeriodicalId":339798,"journal":{"name":"2020 IEEE 4th Conference on Energy Internet and Energy System Integration (EI2)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127424590","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 VCB arc restriking and breaking failure phenomenon appeared frequently in $23mathrm{k}mathrm{A}$ CI tests with arc current fall rate of about $300mathrm{A}/mu mathrm{s}$ for a single VCB, while the VCB CI reliability has been improved a lot under the same conditions with diode connected in series. After a detailed analysis of the vacuum gap (VG) post-arc transient characteristics, it was found that it lasted about $450mu mathrm{s}$ before the VG finishing the ion sheath development for the single VCB in the post-arc stage. Meanwhile, the VG electric field intensity (EFI) and power density (PD) would quickly rise to the peak values of $12mathrm{M}mathrm{V}/mathrm{m}$ and $45mathrm{M}mathrm{W}/mathrm{m}^{2}$ separately in about $1mu mathrm{s}$ after the arc zero-crossing. As a result, the VG electrical or thermal breakdown were very prone to come out when the plasma concentration was still high in the sheath development stage. With the diode in series, the VG power injection path was cut off effectively by the diode reverse blocking, the initial transient recovery voltage rising very fast would be avoid and the plasma concentration was promoted to decay significantly, by which both the EFI and PD were decreased greatly when the VG began to get insulation recovery in the post-arc phase. Under the most extreme condition that the VG started to build dielectric strength at the end of the diode reverse blocking, the simulation results revealed the EFI and PD peak values were substantially reduced to $130mathrm{k}mathrm{V}/mathrm{m}$ and $1.4mathrm{k}mathrm{W}/mathrm{m}^{2}$ respectively and delayed for about $30mu mathrm{s}$, which were very beneficial to reduce the VG breakdown probability and improve the dielectric recovery performance in the post-arc transient.","PeriodicalId":339798,"journal":{"name":"2020 IEEE 4th Conference on Energy Internet and Energy System Integration (EI2)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115416353","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}

Emergency control measures need to be taken to ensure the stability of the receiving-end power grid system. First, according to the different control characteristics of the generator's primary frequency modulation, pumped storage power station, and low-frequency load shedding, the mathematical model of the emergency control strategy is formulated. Then, according to the characteristics of the active disassembly of the power grid, the equation constraints in the model are simplified, and the heuristic algorithm with the participation factor as the basic element is used to calculate how the resources of the strategy are allocated and input to obtain the quantitative indicators of each resource. Finally, the feasibility of multi-resource frequency stability control and section correction control strategies is verified and compared through IEEE39 node simulation. The simulation results show that the coordinated implementation of multiple resources can ensure timely control of the system frequency and minimize the failure loss; at the same time, considering that the power limit is exceeded and the power transfer of the receiving end is too large, the section correction control is proposed Strategy has a great optimization effect.","PeriodicalId":339798,"journal":{"name":"2020 IEEE 4th Conference on Energy Internet and Energy System Integration (EI2)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115712239","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}
