| Abstract | The paper is devoted to water valuation regarding Vietnamese reservoirs in coming competitive generation market. This model is exerted to entire hydropower plants in the electrical power system for the years of 2011 and 2012 year-ahead planning. Water value concept which is regarded as fuel cost of water helps to reflect exploiting cost of water resource in the context of hydrothermal power system. In the other words, water value is perceived as opportunity cost of water utilization at present instead of saving it for alternative usage later. The stochastic dual dynamic programming software that is the most widely used in the world is proposed for modeling purpose. In this context, stochastic feature of incoming inflows is fully dealt with. The trade-off should be obtained between immediate and future operating cost. Based on a state-space formulation, the hydrothermal scheduling problem is decomposed into several one-stage sub-problems where the objective is to minimize the sum of immediate and future operating costs. By running the model, we could obtain the water value of each reservoir that is employed to make a systematically strategic plan of exploiting water sources nationwide as well as foundation for catering bidding strategy in power market. A hydrothermal schedule optimization is also expected to gain, which is applied to classification of generators as peaker, cycler and baseload types. Accordingly, bidding strategy is determined that reflects real operating cost of various generating units. Apart from those, short-run marginal cost assessment forwards three regional power systems is addressed in the context of competitive generation market. |
