This model included a simple level of self-organization by incorporating the growth of power demand and the engineering response to system failures. Two types of blackouts have been identified with different dynamical properties. One type of blackout involves loss of load due to lines reaching their load limits but no line outages. The second type of blackout is associated with multiple line outages. The dominance of one type of blackouts versus the other depends on operational conditions and the proximity of the system to one of its two critical points. The first critical point is characterized by operation with lines close to their line limits. The second critical point is characterized by the maximum in the fluctuations of the load demand being near the generator margin capability. The identification of this second critical point is an indication that the increase of the generator capability as a response to the increase of the load demand must be included in the dynamical model to achieve a higher degree of self-organization. When this is done, the model shows a probability distribution of blackout sizes with power tails similar to that observed in real blackout data,from North America.","PeriodicalId":366006,"journal":{"name":"Proceedings of the 35th Annual Hawaii International Conference on System Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125602706","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}

It envisions short autonomously guided shuttles which are completely automated and even make decisions, for e.g. starting only if there is a need. Furthermore, the shuttles use the existing rails without differentiating between suburban and long-distance traffic. Thus the passengers needn't change trains during their journey. To save energy while driving, the shuttles unite to form convoys. The question is whether it is clever to build a convoy or if the convoy contributes to energy conservation. Afterwards the shuttles have to initiate the integration, to find each other and to execute convoy formation. For these procedures it must be declared for how long the shuttles join the convoy, how they find each other and how they exchange information. In particular, the question of which routes and for which average utilisation a convoy formation makes sense must be asked. The article supplies some answeres concerning the conditions for meaningful convoy travel and how communication between shuttles can be activated and realised.","PeriodicalId":366006,"journal":{"name":"Proceedings of the 35th Annual Hawaii International Conference on System Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126848364","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 arena is already growing diversified with a number of application areas, which are growing in different directions and at different paces. We understand already that B2B, B2E, B2C and P2P will produce rather different types of applications, because the propositions for value-added products and services are quite different. This is probably one of the reasons why the hunt for the “mobile commerce killer applications” has been in vain so far. The applications in B2B and B2E share some value propositions. The key motivation for inter-business applications is to improve the effectiveness and the productivity of the interaction between corporations, companies, business units, etc. and through this interaction process to find new forms of joint/shared products and services, and to find new technological solutions for the corresponding production processes with the mobile technologies. In the B2E applications effectiveness and productivity are worked on for both groups/teams and individuals and mobile systems solutions are focused on (i) boosting mobile worker productivity, (ii) simplifying administrative processes, and (iii) building competitive advantage through simpler and more effective team-work. It is expected that the support technology for these applications will be built around intelligent or smart technologies.","PeriodicalId":366006,"journal":{"name":"Proceedings of the 35th Annual Hawaii International Conference on System Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133952135","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}

Attention is given to strategic bidding of load serving entities (LSE) in these markets. We model energy multi-markets as non-linear dynamical systems and use discrete-time Nash bidding strategies. Attention is given to a problem, where the objective functions are quadratic in the deviations of trajectories from desired trajectories and quadratic in the control deviations from the nominal controls. It is assumed that each power marketer can estimate his/her competitors' benefit functions and their minimum and maximum values. The optimal bidding strategies are developed mathematically using dynamic game theory. We deal with games that are non-linear in the state equations. We linearize these equations for complex non-linear energy multi-markets and use discrete-time Nash strategies. We show that the actual dynamic excursions from the operating point where we linearize are small so that the linearization is valid. The developed algorithm is applied to an IEEE 14-bus power system for two cases: (1) No transmission capacity constraints, (2) Transmission capacity limit constraints on two groups of transmission lines. We show that the LSEs' expected profits are higher for our method than those for other methods in the literature.","PeriodicalId":366006,"journal":{"name":"Proceedings of the 35th Annual Hawaii International Conference on System Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114892087","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}
