Energy management of a system according to an economic market model approach

摘要

An apparatus for energy management of a system according to an economic market model approach, the system comprising a number z of components comprising at least: a number e of energy sources Qa and a number f of loads Lb, with: a ε 1, 2, ... , a1; b ε 1, 2, ..., b1; z = a1 + b1 and j, t ε 1, 2, ..., z; comprising: 1.1. a first means (1001) for assigning to each of the z components of the system an individual price-to-performance relation PRj which allocates prices from the respective j-th component, each of the price-performance relations PRj being indicated by a curve kj in which power values lj output or recorded by the respective j-th component are plotted against price values pj, where at least one such price-performance relation PRj = t is represented by a non-monotone such curve kt *, and all other price values Power relations PRj ≠ t be represented by monotone such curves kj ≠ t, 1.2. a second means (1002) adapted and adapted to approach the non-monotone curve kt * by a first monotone approximation curve Kn = 1, t, thus providing a first monotone approximation relation Nn = 1 (PRj = t) for the non-monotonic price Power relation PRj = t, where the approximation curve Kn = 1, t is determined in such a way that for all points (lKn = 1, t, pKn = 1, t) of the approximation curve Kn = 1, t: the power value lKn = 1, t for a price pKn = 1, t is greater than all power values lkt * of the non-monotonic curve kt * at this price pKn = 1, t, and the approximation curve Kn = 1, t is the curve which is the lowest under the above condition Difference to the non-monotone curve kt *, 1.3. a third means (1003) executed and arranged on the basis of z price-performance relations PRj, wherein instead of the price-performance relation PRj = t the first approximation relation Nn = 1 (PRj = t) is used, a first equilibrium price pn = 1 and determine an associated equilibrium power ln = 1 for the system, 1.4. a fourth means (1004), adapted and adapted to approximate the non-monotone curve kt * by another monotone approximation curve Kn + 1, t, thus providing an n + 1th monotone approximation relation Nn + 1 (PRj = t) for the not monotone price-performance relation PRj = t represents, whereby the following steps are executed: ...
