Electrical energy is exchanged with the power grid, operated by an external utility, with different purchasing and selling costs set by Authorities and Facilities. Due to the different request of electrical power by user, these cost coefficients, expressed in €/kWh or $/kWh, are changing through the day and during the week. Dynamics of energy costs is ruled by free energy market which originated by deregulation process started during ‘90s.

Abstract
The increasing cost of energy and the introduction of micro-generation facilities and the changes in energy production systems require new strategies to reach their optimal exploitation. Artificial Immune System (AIS) metaphor can be used to reach this aim. In this kind of management, the energy system can be seen as a living body which must react to external stimuli (cost of fuel, energy prices, fares, etc.) fulfilling its internal requirements (user loads, technical constraints, etc.). In this chapter, a developed procedure based on AIS is described and applied to this problem. Its performance is compared with the mixed integer linear programming on the same test. The result shows that AIS based method obtained better results, in terms of computational efficiency, compared with classical energy production management procedures based on Mixed Integer Linear Programming.
