Current tracking control of inverter is very important because current control ability affects control performance of plants. In this paper, the robust current control method of voltage source PWM inverter is presented; current is controlled to be exactly equal to the reference current under variations of load parameters and operating conditions. The influence of parameter variations is restrained by feedback gain based on Lyapunov's direct method. The feedback gain is calculated on-line to ensure system's stability with various disturbances.","PeriodicalId":262115,"journal":{"name":"Electric Machines and Power Systems","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121327633","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}

Likely profit from the development for electricity supplied to the UK considering alternative routes, varying discount rates, possible carbon/fossil fuel levies, and fossil fuel emission constraints are illustrated in the comparisons that are made. It is concluded that power from Iceland is viable in all but the most exacting scenarios and the best landing point for the cable is the North of Scotland. There are no technical reasons why the Link should not proceed. There would not seem to be significant advantages in tying in existing national markets in The Netherlands and Norway at this time should the development go ahead. The Link should be designed for base-load operation at high load factor, and the most advantageous return on capital em...","PeriodicalId":262115,"journal":{"name":"Electric Machines and Power Systems","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128678770","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 capabilities of flexible ac transmission systems (FACTS) equipment are not only constrained by their thermal limits and the steady-state security limits, but also limited by their feasibility limits. After the detailed analyses have been made on the use of optimal multiplier u as a new predictor to estimate the boundary point of the feasibility region, an algorithm for deteiTnirung the UPFC regulating capability is proposed. The approach is then compared with minimum singular value decomposition on the IEEE 30 bus system. The results clearly demonstrate the effectiveness of the proposed approach.","PeriodicalId":262115,"journal":{"name":"Electric Machines and Power Systems","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133012837","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}

A multi-area unit commitement model based on Capacity Utilization Factor(CUF) and sequential techniques including dc(direct current) power flow module is developed to estimate the constrained(both system and transmission)inter-area energy exchange and its associated production cost. The model is applied to a vast and complex Indian Power System with two different areas having different operating characteristics.The validity of the model is tested by comparing the solutions with those obtained by a multi-area combined Truncated Dynamic Programming (DP-TC) based method. The results indicate that inter-area energy exchange leads to a better optimal power system operation and substantial cost savings may be achieved by utilizing the low cost energy resources and reserved energy in one area to another area which has higher cost of energy production.","PeriodicalId":262115,"journal":{"name":"Electric Machines and Power Systems","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123983227","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 model concentrates on the open loop transfer functions of induction machines for small perturbations in motor speed and firing angles.
