SMART GRID-Control for Kolding Central WWTP
An automatic Smart Grid System for Kolding WWTP shall, on the basis of a prognosis for the future wastewater load, a prognosis for the future variation in energy prices, the present operational status, and a risk assessment, be able to automatically determine the future operation of selected energy consuming units on the treatment plant, including optimization of the internal energy production.
Smart Grid control software will be installed at Kolding Central Wastewater Treatment Plant (KCR). The purpose of the control is to automatically optimize the energy consumption and production in the plant in relation to variations in energy prices, inflow and effluent quality. The aim is to ensure that externally bought energy is primarily used when energy prices are low, in order to reduce the energy consumption in periods with high energy prices.
The control software will also be developed to give a forecast of the run-off in the sewage system so that the system can be utilized as buffer capacity, considering the expected dry weather and rain periods, and thus contribute to redistribution of the energy consumption.
The project consists of 2 main phases where the software is developed, tested and commissioned successively, starting with the energy consuming processes in the treatment plant, then optimizing the run-off from the sewer system and finally optimizing the energy production from the biogas in the treatment plant.
