Method and apparatus for automatic extension of a range of production

The solution described here belongs to the field of optimizing production schedules under consideration of energy flows.

The starting point are existing procedures for optimization of production schedules with respect to a given objective function under consideration of the production factor energy.

In the known methods, the energy used for production, especially electrical energy, or the emission of CO2 are treated as limiting factors for production.   

In contrast to this, the understanding of the term “production” is extended to include positive and negative energy-/CO2-flows. Their quantization can be seen as a product, in the form of energy packets or CO2-packets. Therefore, the range of the production portfolio is extended automatically. The optimization of the production process aims not only at optimizing the original or actual production itself, but takes into account also the additional amount of energy packets/CO2 packets which can be produced and delivered.

Both forms of production, the original production and the production of energy packets/CO2 packets, differ in their ordering. While the original production with orders placed by customers has usually fixed delivery dates, the energy/CO2-packet products are traded according to the actual market situation at the corresponding stock markets or in the corresponding transaction system. Thereby, the production of energy/CO2-packets depends on the production of the original product. The increasing integration of renewable energy sources - which have among others the characteristic to be weather-dependent - into the energy market, results in an increasing and more volatile demand for positive and negative balancing energy. This has an effect on the traditional power plants, too. These plants - like e.g. coal power plants - are producing high amounts of CO2.

The variability can have a shorter time horizon than the usual production schedule resulting in a higher dynamical behavior of the production scheduling. In contrast to classical Demand Site Management / Demand Response measures, the grade of the dynamical behavior is many times higher. Therefore, in contrast to for example load shedding, the negative implications of the original production can be neglected.

The solution is based on the following considerations:

·         integration of the energy production (e.g. industrial energy production plant) into the energy market, without negative effect on the original production;

·         seizing of opportunities to react to actual electricity-/gas-grid demands via load control;

·         possible use of electrical motors for frequency control.

          

The steps presented here are related to the product of energy packets. They can be obtained in an analogue way for CO2-packets.
