In the area supplied by Stadtwerke Ludwigsburg-Kornwestheim public utility, we implemented an intelligent and fully coordinated solution that automates the entire local and district heating supply from the transfer station controller to the central SE²OPERATOR control system via the freely configurable SE²MASTER energy center control equipped with the "Cluster Control” function module.
Hybrid combinations of modern CHP units, gas peak load boilers, heat pumps, wood pellet boilers and a large number of heat storage systems are currently in use in 22 different energy centers. In addition, a wood-fired cogeneration plant feeds into the district heating network and, as of May 2020, into Germany's largest ground-mounted solar thermal plant, which is setting new standards with a peak output of about 9 MW and a collector area of 14,800 square meters. This plant is combined with a 2,000 m3 heat storage tank and the merging of four heat networks.
As a result, we now regulate a total installed capacity of over 140 MWth and more than 10 MWel with a total heat network length of 67 km.
Thanks to the wide use of renewable energy sources and modern CHPs, more than 45,000 tons of CO2 are saved each year.
- Consistent, coordinated system solution with a homogeneous communication infrastructure
- Higher-level control technology enables remote access to the energy centers and transfer stations
- Transparency in the overall system allows the operator to monitor the plants at any time and provides detailed information on their status
- High supply reliability and flexibility
- Efficient and economical plant operation through optimized capacity utilization
- 3 electricity price-based generators increase profitability and create additional revenues in the virtual power plant market
- Remote maintenance and on-call service enable diagnosis and fast support since all systems can be accessed centrally
