Sažetak
Today’s Power System is very developed as the most complex contemporary technical systems. It has very long tradition in developing, more than a hundred years. Many mathematical models were developed and used to describe all the aspects power system, from technical to economical or ecological points of view. Usually, mathematical models were formulated through the objective function, which contains all fixed and variable costs of generation, transmission and distribution as well as costs of investment into new generation, transmission and distribution facilities. The solution of objective function was the lowest total costs of power system i.e. That algorithm is known as Least cost planning (LCP). A broader view of transition would mean that the period of concept of the LCP ended with the introduction of electricity market. In the last decades of a hundred-year development of power system there was an intensive shift of acceptable technologies for electricity generation towards renewables to lower CO2 emission. To speed up investment in renewables electricity generation incentive system was promoted since those technologies were not market-effective or economic. It seems that today after decades of development these technologies have become economic. However, after major construction of windfarms and solar power plants, we learned that the generation characteristics of those technologies have a significant effect on power system regarding necessary additional reserve capacities as well as balancing capacities to maintain security of supply. Technologies for storing electricity appeared, for instance batteries, which marks an additional cost. In order to intensify the construction of renewable energy sources CO2 emission tax was introduced, not being a market mechanism, but a political instrument, which is also an additional cost. The construction of small sized solar power plants has been intensified, which is not economic and entails additional cost for distribution system. There are some new technological solutions such as hydrogen generated from electricity with various possible usage. This can be, and probably is, ecologically justified, but it is hardly economic (without incentives). The measure of successful share of renewables in energy sector is the portion of electricity from renewables over final energy demand and it is hardly to say objective analyze. If we analyze the whole power system today, it seems that the Transition towards imaginary power system with zero CO2 emission is beyond the logic of the law of economy.
