A small-signal model of lead acid battery is derived in detail to design the employed dual-loop control configuration. Two case studies are then conducted, in SIMULINK/SIMPOWER, first to evaluate the performance of the designed controller in terms of transient response and voltage overshoot. Secondly, realistic irradiance data is used to evaluate the performance of the developed charge controller in terms of parameters such as PV energy utilization factor and over-voltage compared to the conventional hysteretic on/of controller. The designed controller is demonstrated to have good transient response with only small voltage overshoot. It is also found that the developed charge controller fares better in terms PV energy utilization and shows at least the same level of over-voltage control.","PeriodicalId":403158,"journal":{"name":"2011 International Conference on Clean Electrical Power (ICCEP)","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129025127","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, most of present distribution networks have been designed as passive networks and present some relevant problems that prevent a strong penetration of DG. One of the major problems is the voltage rise due to active power injections made by distributed generators. This paper reviews control strategies that have been recently proposed to control the voltage profile of distribution networks and to mitigate voltage rise. A voltage rise mitigation strategy is then presented along with a mathematical formulation that encompasses both coordinated and local reactive power generation controls. A proposal for an implementation using smart control devices of the distributed generators is finally presented.","PeriodicalId":403158,"journal":{"name":"2011 International Conference on Clean Electrical Power (ICCEP)","volume":"293 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":"116570636","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 approach is practically founded on a fast incremental algorithm. The latter requires the definition of an objective function which is based in the present case on the definition of a Pearson correlation coefficient level. The advantage of such a clustering methodology is mainly perceptible in large scale electrical systems with increased wind penetration. Indeed, it allows to group together highly correlated wind parks into the same cluster and to integrate them in a realistic way into a non sequential Monte Carlo adequacy evaluation process. Here, the proposed clustering methodology is applied to 94 wind sites located in Occidental Europe. Then, in order to point out the efficiency of the proposed clustering methodology from the wind speed sampling point of view, an adequacy study is applied to the Roy Billinton Test System in the particular case of a single wind cluster.","PeriodicalId":403158,"journal":{"name":"2011 International Conference on Clean Electrical Power (ICCEP)","volume":"17 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":"128319662","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}

With the increase in penetration level of renewable energy resources, uncertainties in the power output of these types of power plants should also be considered by TSOs. Since the output of these types of power plants could not be estimated accurately, the reserve that should be kept for proper operation of power system could be determined with probabilistic approach. In this paper, standard deviation and Weibull distribution are used to estimate the amount of operating reserve required for wind power plants.
