The self-scheduling requirements and interactions between the energy and reserve markets are considered. A Lagrangian relaxation based algorithm is then developed to solve this problem, and a stochastic dynamic programming approach is developed to solve the unit subproblems. Since the bidding of pumped-storage units plays important roles in both the energy and reserve markets, and significantly affects thermal biddings, it is the focus in this paper. Effects of self-scheduling constraints, risk management and reserve market on the energy bidding strategies are analyzed. Numerical testing based on an 11-unit system in New England shows that the method can generate energy and reserve bid curves in 4-5 minutes, and risks of buying power at high market price are effectively reduced

Se parte del auge del movimiento teatral en la década de 1970 y el decaimiento y la crisis en las últimas dos décadas. Se procura ubicar la producción de los textos dramáticos, los conflictos, la temático y algunas características formales de esos textos, dentro del desarrollo de las artes escénicas y la representación teatral en Costa Rica, y dentro del contexto histórico y cultural del país.
