The response surface methodology (RSM) is used to achieve the objective function of the optimization problem. The validity of the system is proved by the simulation results which are achieved using PSCAD/EMTDC. The system is studied under three different operating conditions which are 1) system conversion from grid-connected to islanded mode, and 2) three phase faults during islanded mode. The validity of the proposed controller is proved by comparing its results with the particle swarm optimization (PSO) method results.","PeriodicalId":244426,"journal":{"name":"2020 2nd International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130767822","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}

Based on the actual load of a hospital in Shanghai, the research shows that time-of-use price mechanism can significantly reduce the investment and operation cost of CCHP, improve primary energy efficiency, and guide CCHP to participate in peak load shifting.

However, the special fault characteristics of DC system bring challenges to protection such as: 1) Due the complex structure of flexible DC distribution system with multi-terminal distributed photovoltaic, the protection cannot set a clear boundary using single-ended measurement. 2) The DC faults last about several milliseconds and its fault characteristics controlled by power converters’ variable control algorithms, thus causing the difficulty in fault location. Therefore, a novel fault detection and location method-based protection scheme is proposed to deal with these issues. The proposed method utilizes the coordinated control between local protection and the converters in the system, eventually, the problem of unclear protection boundary was solved. Meanwhile, the proposed protection method can distinguish the correct faulted area by calculating harmonic impedance of these characteristic signals. Simulation results show that it is effective to achieve the combination of control and protection through the well controllability of power electronics. The principle is simple and reliable.","PeriodicalId":244426,"journal":{"name":"2020 2nd International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"197 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123530863","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 the evaluation purposes, two major locations, such as the AC grid or DC grid, are considered for the BESS. The detailed dynamic model of the test HMG system is simulated under various disturbances cases when the BESS is operated either in AC or DC subgrid.

The trending use of expensive, but more efficient and maintenance-free lithium-ion batteries in millions of light vehicles such as golf carts will decommission a large amount of existing lead acid batteries to be used for electrification purposes at a much lower cost. These used batteries in their second life can significantly reduce the storage cost of electrification in off-grid systems or in the most demanding business activities such as powering vendor handcarts and community shops. Though, the used batteries are sold at a cheaper price, they still require costly equipment and time-consuming tests to evaluate if and for how long they can be re-purposed. This paper is prepared to propose a rapid, low cost, and bulk test procedure for lead acid battery characterization, capacity measurements, and restoration without any of their known history or datasheet using deep cycling process. Parameters are suggested to help in the remaining life identification and to qualify these batteries for grouping in power packs based on their health and capacity. Finally, a process to review test results and make appropriate decisions regarding battery reuse or recycling is provided.","PeriodicalId":244426,"journal":{"name":"2020 2nd International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122390792","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 CAES system is connected to the load through a boost converter that controls the air motor’s speed to achieve maximum power point tracking (MPPT). A bidirectional converter is used to connect a battery to the load and maintain the output voltage constant. The air motor and battery sizes are estimated for a typical house in the Southern region of the UK. The battery is sized to buffer load fluctuations. All system models have been simulated using MATLAB/Simulink. Two scenarios are considered: a CAES only system controlled in constant voltage mode and a hybrid system comprising CAES with an MPPT controller and a battery with a voltage controller. The results demonstrate that the power rate of air motor is estimated properly by considering the difference between the generated power and demand power. The power difference called energy deficit is used to size the battery. The performance of CAES system is improved by hybridizing with a battery; the system maintains constant voltage when the CAES operates at maximum power point (MPP). The air motor in hybrid system controlled in MPPT mode has approximately 47% greater efficiency than that of air motor controlled in voltage mode.","PeriodicalId":244426,"journal":{"name":"2020 2nd International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"179 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124461190","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}
