3 Sanoat va tijorat zaxiralari stsenariylari: katta salohiyat va moslashuvchan rejalashtirish
Evropaning "Yuqori kuchlanishli klaster energiyasi saqlash eritmasi". A 600V/5MWh high-voltage rack mounted lithium battery cluster in Germany (consisting of 5 1MWh modules) adopts a "master-slave control" architecture: one central controller (response time<10ms) uniformly receives grid dispatch instructions and dynamically allocates charging and discharging power to each module (deviation<1%). Support "multi period charging and discharging plan" (8 periods can be set), adapted to the peak and valley electricity prices of industry and commerce (0.5 euros/kWh during peak hours, 0.1 euros/kWh during valley hours): full power charging during valley hours (00:00-06:00), full power discharging during peak hours (10:00-12:00, 16:00-20:00), with an annual arbitrage profit of 180000 euros. At the same time, the cluster has a "reactive power compensation" function (with a power factor of 0.8 leading to 0.8 lagging), which improves the power quality of the factory. After being applied in a certain automotive parts factory, the power factor was increased from 0.75 to 0.95, saving 12000 euros in monthly power adjustment electricity costs.
