Different UPFC control pattern for different optimal power flow calculation needs was present and analyzed. In each control pattern, only one parameter of UPFC series component is introduced and in these cases the gradient based OPF algorithm has a good performance similar to the cases without UPFC control. UPFC steady state model under these control patterns is set up. A direct non-linear interior point method is employed to implement the OPF problem. The OPF problem with these UPFC control patterns is tested by examples with multiple UPFC devices. Combination cases were also studied. Results show the effectiveness of this method.","PeriodicalId":236779,"journal":{"name":"IEEE Power Engineering Society General Meeting, 2004.","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132086715","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}

In this work an update on two selected superconducting FCL projects is given. Successful testing of resistive type prototype three-phase devices at voltages up to 10 kV are reported. While such tests clearly indicate the technical feasibility of novel FCLs for medium voltage applications, several system integration issues are still not addressed properly. The paper discusses the need for standard FCL testing procedures and important impacts of FCL on existing and future power system protection systems. It is concluded that novel medium voltage FCLs may lead to substantial benefits on future all-electric navy ships from significant reductions in weight and size of equipment. Furthermore, it is proposed to study more thoroughly the impact of FCLs on protection systems by means of transient system simulations.","PeriodicalId":236779,"journal":{"name":"IEEE Power Engineering Society General Meeting, 2004.","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122279555","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}

Optimal placement of multiple FACTS devices will naturally control the overall reactive power requirements. But the mathematical complexity and hence the solution time increases for reactive power planning of large power networks with multiple FACTS devices. To obtain a feasible and suboptimal solution for reactive power planning, optimal location of FACTS devices and its parameters have been determined using simple genetic algorithms. Genetic algorithm, performed on two parameters: the optimal location of the devices and their control parameter and then the fitness function has been determined using quasi-Newton algorithm based optimal power flows for minimization of reactive power losses and generations. The performance of the proposed algorithm has been tested for IEEE-30 systems with multiple TCSC devices. It has also been observed that the proposed algorithm can be applied to larger systems and do not suffer with computational difficulties.","PeriodicalId":236779,"journal":{"name":"IEEE Power Engineering Society General Meeting, 2004.","volume":"18 8","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120916108","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 aim is to address voltage collapse problem in government-owned utilities in West Africa. Since then it had grown to cover wide geographical areas including Eastern, Central and Southern African countries. In addressing some of the challenging problems on the African continent, the biennial conference proposal was modified to embrace a research component between US and African power engineering academia.

Its system is essentially designed from a centralized viewpoint. But from 1990, different factors (such as liberalization of the market, technological progress, economic incentives, environmental constraints...) have led to a strong development of dispersed generation, which has to be taken into account in an integrated resources planning approach. Historically, energy is provided by centralized sources from the transmission grid to the distribution one. An important share of dispersed generation would modify the flows and make new constraints on the distribution grid, which was not designed to work so. This work quickly describes the structure and the actors of the French system. Then it presents the consequences of the growth of dispersed generation, regulatory issues, possible scenarios of evolution (percentage of dispersed generation in the whole system capacity), and the ongoing research projects to deal with this new question.","PeriodicalId":236779,"journal":{"name":"IEEE Power Engineering Society General Meeting, 2004.","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131168645","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}
