  • As an electricity industry transforms into a competitive system, an electricity market revolves into a combined market consisting of generation and operating reserve. This paper presents a market model combined by an energy market and an operating reserve market. In a competitive structure, Gencos strive to choose strategic bidding parameters that maximize total profit resulting from an energy market and a reserve market. The primary goal of the paper is to analyze power transactions of generation and operation reserve based on marginal profits and capacity limits at NE(Nash Equilibrium). In case studies, the reserve market and the energy market are compared at the n from the viewpoints of marginal profits, prices and transaction quantities. It is shown that the marginal profit in an energy market is equal to that in a reserve market, and Gencos strategic bidding is greatly influenced by capacity limit.

  • As the world population increases and technology advances, the energy consumption and need for more energy increase. Communities and governments regularly address these needs and set policies for future energy generation and uses. This paper reviews current energy policies of the USA and the current trends in research and development efforts, for sustainable and renewable energy sources. Furthermore, the recent topic of IEEE's Smart Grid initiatives is discussed, and its role in the dielectrics and electrical insulation research is presented.
