For this isolated system, a photovoltaic (PV) array installed at the parking roof is in charge for power supply. Also, a battery bank as a storage system is dedicated to ensure the service continuity. A step down DC/DC converter is providing the required voltage to harvest the maximum available power of the PV array. This converter is fed by the main system DC bus. Another bidirectional DC/DC converter is responsible to maintain the suitable voltage profile at the DC bus, in addition to the battery charging. The last stage of the supply is a voltage source converter (VSC) that is fed by the main DC Bus. All three converters are designed and modelled. Further, the appropriate controller for each converter is suggested. Considering the importance of the VSC output filter, an efficient algorithm for filter design is proposed that offers better trade-off between filtering and damping. Also, a controller is suggested for bidirectional buck-boost converter that guarantees its stable operation for sudden change of PV supply and load, for the whole operating region. The effectiveness of the proposed design procedure is validated through time-domain simulations.","PeriodicalId":265297,"journal":{"name":"2018 IEEE Electrical Power and Energy Conference (EPEC)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131212951","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 proposed power generation system drives the actuator by making use of large pressure difference in the generation and dissociation reaction of CO2hydrate caused by small temperature difference of several tens of degrees. In this study, CO2hydrate generation and dissociation tests are carried out using reaction vessels with different thermal conductivity, and the C02 hydrate generation characteristics are compared by examining the CO2hydrate generation amounts. In addition, an increase in the power generation amount of the proposed system is analyzed. Experiments were conducted to examine the production experiment of CO2hydrate to measure the amount of CO2hydrate production and experiments simulating the proposed system using reaction vessels and buffer tanks. A stainless steel cylindrical device (thermal conductivity 20.9 W/(m·K)) and a copper cylindrical device (thermal conductivity 402 W/(m·K)) were used for the reaction vessel. By using two reaction vessels, we investigate the amount of CO2hydrate produced and the efficiency of dissociation due to the difference in thermal conductivity. As a result of the survey, it was confirmed that increasing the thermal conductivity of the reaction vessel increases the CO2hydrate production by about 67% and the CO2 hydrate dissociation efficiency increases by about 1 %. Therefore, as one method to increase the power generation amount of the proposed power generation system, it is possible to increase the thermal conductivity of the reaction vessel.","PeriodicalId":265297,"journal":{"name":"2018 IEEE Electrical Power and Energy Conference (EPEC)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134343263","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 paper proposes a modified power mismatch elimination strategy for an MMC-based PV system. Although the existing power mismatch elimination strategy based on internal power flow of the MMC is capable of eliminating power mismatches in a perfectly balanced power system, it will fail to do so if the grid voltage is unbalanced at point of common coupling (PCC). The proposed modified power mismatch elimination strategy, utilizes the internal power flow of the MMC-based PV system to ensure that the converter leg connected to grid phase with higher voltage delivers higher power to the grid and the leg connected to the phase with lower voltage delivers less power to the grid. As a result, the currents delivered to the host grid become balanced and symmetrical in spite of existing power mismatches and unbalanced grid voltage. The effectiveness of the proposed modified power mismatch elimination strategy is demonstrated by time-domain simulations conducted on a model of the PV system in PSCAD/EMTDC software environment.","PeriodicalId":265297,"journal":{"name":"2018 IEEE Electrical Power and Energy Conference (EPEC)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114139066","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}

These generators are sited at resource-rich locations, causing a geographical shift in power injections into transmission systems, in some cases, subjecting them to undue stress. In many transmission systems, the capacity to integrate wind resources has been exhausted. In these circumstances, assessing the effect of the uncertainty inherent in wind forecasts with respect to system voltage stability is very important. This paper proposes a method for providing such an assessment. Using an optimal power flow algorithm, a Hessian matrix of the power balance equations is determined, which linearly relates changes in the minimum singular value of the system Jacobian to changes in bus-wise real power injections. This relationship is then employed for examining the effect of the uncertainty in the wind power forecast with respect to system voltage stability. The proposed method has been applied for studying these effects in IEEE 6-bus, 57-bus, and 118-bus systems. The same systems were also investigated using the minimum singular values of the system Jacobian matrix. The comparison of results from two methods demonstrates the effectiveness of the proposed technique.","PeriodicalId":265297,"journal":{"name":"2018 IEEE Electrical Power and Energy Conference (EPEC)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125358512","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}
