AI Technical Summary
Wastewater treatment plants have high energy consumption in their aeration systems and cannot effectively control carbon emissions. The absorption rate of photovoltaic green electricity is low, and the utilization rate of energy storage equipment is insufficient, resulting in a high proportion of electricity purchased from the grid during high-carbon periods, making it difficult to achieve low-carbon and efficient operation.
A collaborative scheduling model is constructed with the goal of minimizing total carbon emissions over the entire life cycle. It integrates multi-source input data such as the initial operating status of the wastewater treatment plant, photovoltaic power generation, dynamic carbon intensity of the power grid, influent flow rate and water quality to achieve coupled solution of the process side and energy side. Through the linkage calculation of dissolved oxygen setpoint and energy storage charging and discharging power, the collaborative scheduling of the aeration system and the photovoltaic-storage system is optimized.
It improves the local consumption rate of photovoltaic green electricity and the utilization rate of energy storage equipment, reduces the purchase of electricity from the grid during high-carbon periods, achieves precise control of carbon emissions of the entire plant, and takes into account both the requirements for meeting the water quality standards of wastewater treatment and the goal of low-carbon and efficient operation.
