To assess the value of coordination in a realistic setting, we develop a multi-stage stochastic program for day-ahead bidding and hourly intraday trading along with a corresponding stochastic price model. We show how tight upper bounds can be obtained based on calculating optimal bi-linear penalties for a novel information relaxation scheme.
Economic Evaluation of Grid-side Energy Storage Trading on Multiple Electricity Markets Abstract: The rapid growth of renewable installation poses new challenges to the stability of power grids. Energy storage is a promising technology to reduce the impact of high renewable penetration.
Additionally, most of the previous work has focused on the support function of the grid forming CIG with DC side energy storage, after being subjected to a large disturbance. However, besides this transient response, the CIG should also mitigate the effect of the stochastic variation of the renewable generation on the frequency variance
With the transformation of China''s energy structure, the rapid development of new energy industry is very important for China.
