power and the need for balancing reserves. A recent study (Ikegami Lab at TUAT) explored how water distribution systems (WDS), particularly water pumps, can help balance supply and demand by shifting their operation times.<\/p>\n\n\n\n<p><strong>Key Points:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A model was developed to analyze power supply and demand, including water distribution units.<\/li>\n\n\n\n<li>Water pumps can shift their operation times to provide Load Frequency Control (LFC) reserves.<\/li>\n\n\n\n<li>Water distribution systems across Japan were categorized into four types and modeled.<\/li>\n\n\n\n<li>The potential of water distribution systems to respond to demand in Japan was evaluated.<\/li>\n<\/ul>\n\n\n\n<p>The study simulated the operation of water pumps in 2040, showing that by adjusting their pumping schedules, water pumps can reduce surplus power, lower fossil fuel costs, and decrease the curtailment of renewable energy output.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Water pumps can reduce surplus power, lower fossil fuel costs, and decrease the curtailment of renewable energy output.
