Interconnected Systems

Power systems operate on either AC (50 Hz), or AC (60 Hz). Interconnection can be implemented based on an AC/AC or AC/DC basis. Technical, economical, and environmental considerations must be investigated to establish the best interconnection configuration. Moreover, the social, legal, and political impacts are of potential importance and must be considered.

‘The business of business is business,’ Milton Friedman, a leading figure of the Chicago School of economic thought, famously declaimed. In his 1970 article, ‘The Social Responsibility of Business Is to Increase Its Profits’, he argued that corporate managers who factor social and environmental considerations into their decision-making are, in effect, ‘imposing taxes . . . and deciding how the tax proceeds shall be spent’. By deviating from their organizational duties—maximizing profits for the companies that employ them—they are appropriating money owed to shareholders and allocating it to broader social causes, a function that resembles government. Friedman objects to this behavior not on economic or legal but on political grounds: managers have not been elected and there are no principled procedures for determining which causes to support beyond ‘general exhortations from on high’ (Friedman 1970: 17). He also expresses scepticism about ‘hypocritical window-dressing’, concluding: ‘our institutions, and the attitudes of the public make it in their self-interest to cloak their actions in this way’ (Friedman 1970: 17).

Power systems contain four generic parts, including production, transmission, dispatch distribution, and consumption. Generally, dispatch distribution between powerhouses modelled with the goal of minimisation in utilisation cost. However, Environmental concerns were given more attention to powerhouse emissions such as SO2, CO2 and NO cause to investigate modelling in recent researches. However consideration of the objectives of fuel cost and emission value in the dispatch distribution problems known as the eco-environmental dispatch distribution. Although Due to the paradox between the reduction of utility costs and external costs, different methods used.

Demand response (DR) is one of the major stakeholders in the smart grid and has been used as an energy reconciler between supply and demand. After a literature overview, the importance of the paper is enhanced by having a theoretical and behavioral-based analysis of DR in power systems. In this work, the potential factors that influence more DR among customers and the residential market as a whole have been discussed. The customers’ elastic demand approach can pave the way for adapting a responsive demand mechanism that ensures the system reliability and cost effective measures. Alternatively, this approach can make the program more effective and supportive in serving the social welfare as whole.

The international trend of interconnecting electric power systems has two dimensions; economical and technical. Electric power systems in the Arab World are not only eligible, but in need for having a unified power grid. The potentials, status and conditions of the existing and future interconnections in this region are overviewed. The development of the six countries interconnection project, including the completed phase of Jordan-Egypt submarine link, is discussed in details. Finally, the main technical problems, which either faced the first stages of the project or expected to face the interconnected systems in the subsequent stages, are highlighted.

This book has introduced the social-symbolic work perspective, which revolves around the relationship between social-symbolic work and social-symbolic objects. To explore this relationship, it examined three broad forms of social-symbolic work—self work, organization work, institutional work—and prominent streams of management and organizational research associated with each. This concluding chapter moves on to a broader set of questions concerning the potential importance of a social-symbolic work perspective for different communities. In particular, it explores the implications of the social-symbolic work perspective for scholars analyzing the social world, change-makers trying to make it better, and citizens trying to understand and cope with its roaring currents of change.
