This assignment delves into the operational challenges faced by China's rapidly expanding hydropower systems. It explores energy-saving measures and emission reduction strategies, drawing insights from various sources such as 'Renewable and Sustainable Energy Reviews' (Cheng et al., 2012) and 'Electric Energy Systems: Analysis and Operation' (Expósito et al., 2016). Additionally, it considers demand-side management in smart grids with electric vehicles (López et al., 2015), optimal operation management of distribution networks (Niknam et al., 2011), and co-operative management of local fisheries (Pinkerton, 2011) as related context.
