The proposed method is based on the dependency of the phase current slope that achieve from AM with DSP technique. These estimators may be utilized to remove sensors for cost reduction as well as back up virtual sensors in a fault resilient drive.

Unfortunately, a systemic design of these converters is not easy, since many parameters related each other heavily affect the dynamic behavior and the efficiency of the converter. An optimization procedure is proposed for choosing the fundamental parameters of both converter and control law based upon sliding control technique. Sliding mode control has been selected for its well known properties of robustness against disturbances and modeling uncertainties. The core of the procedure is an analytical model of the power losses which in the optimization algorithm is the goal function. Some considerations are specifically performed with respect to the sliding mode existence. The numerical results reported in the paper permit to confirm the feasibility and the goodness of the proposed design and control methodology.","PeriodicalId":403158,"journal":{"name":"2011 International Conference on Clean Electrical Power (ICCEP)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114110693","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}

Morello","doi":"10.1109/ICCEP.2011.6036294","DOIUrl":"https://doi.org/10.1109/ICCEP.2011.6036294","url":null,"abstract":"In the paper it is shown that grid-connected PV-plants can be considered and profitably used for powering greenhouses. In fact, in a PV-plant to be installed in a greenhouse, PV-modules can be simply and fully integrated on the greenhouse coverage so allowing to obtain the maximum government economical incentive for generating electricity, also minimizing authorization and tax problems that are more stringent both for large “on-ground” and “on-roof” residential or industrial PV-plants. However, in greenhouse PV-plants with PV-modules integrated on the coverage, the consequent shading effect could limit photosynthesis phenomenon, leading to serious problems related to crop productivity. Transparent or semitransparent technologies for PV-modules don't fully obstruct the incident light and don't stop the photosynthesis in greenhouses; then, they can represent a very good solution for reducing negative impact on the crop productivity of shading effect. On the other hand, they are significantly more costly than conventional PV-modules and this may limit their utilization in large-power PV-plants. In this paper, on the basis of progress of a research project that is developing by the authors with the financial support of the “Regione Calabria - Italy”, a novel greenhouse prototype, powered by a PV-plant, is introduced. It is essentially based on a conventional cost-effective PV-plant that generates electricity to be used for fully supplying both an artificial lighting system and a heating/cooling system, properly designed for the optimal control of the greenhouse micro-climate and for maximizing the greenhouse crop productivity. Comparisons with already experienced different solutions are also developed.","PeriodicalId":403158,"journal":{"name":"2011 International Conference on Clean Electrical Power (ICCEP)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114197902","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}

Among the loads, heat pump is focused as a device which its power consumption may be controlled from the grid operator, because when the interval of the compensated power fluctuation by the heat pump is short enough, fluctuation of room or water temperatures would be kept small, thus users' convenience can be maintained. In this paper, experimental results of controlling the heat pump's power consumption are shown. The experiments were conducted to evaluate the chacteristics of the power consumption response to reference signals, and the response characteristics of the processed heat. Using the data of the response characteristics of the processed heat, evaluation of the fluctuation of the room temperature was done by simulation. By these analyses, the amplitude and the period of the power fluctuation which the heat pump can be used to compensate are shown.","PeriodicalId":403158,"journal":{"name":"2011 International Conference on Clean Electrical Power (ICCEP)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123756110","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}

Such a plant works in island mode and is composed of: a wind turbine, a photovoltaic generator and a fuel cell/electrolyzer energy storage system. The performances of the proposed strategy are evaluated by simulation in different operating conditions. To this purpose some performance indexes are considered, such as: the frequency deviation, the stability of the DC bus voltage and the AC voltage total harmonic distortion. Simulation results confirm the effectiveness of the proposed power management strategy, providing the ground for the practical realization of a fuzzy logic based control system. Moreover the efficiency of the developed fuzzy logic controller is compared to that of a more conventional controller taking into the fuel cell H2 consumption, the amount of H2 generated from the Electrolyzer and the final battery state of charge (SOC).","PeriodicalId":403158,"journal":{"name":"2011 International Conference on Clean Electrical Power (ICCEP)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129440147","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}
