Electricity Consumption Management In A
Competitive Electricity Market

Abstract
A power system is characterized by the nonuniform nature of electric energy
consumption. In the competitive electricity market, the electric energy cost is the
spot one, which is determined for every fixed time interval and can significantly
differ with the hours of maximum and minimum loads, on business and nonbusiness
days, etc. The consumer is primarily interested in reducing the energy
consumption during the peak load hours and shifting it onto the off load periods,
which results in load leveling and allows for energy saving.
To solve the problem of improving the energy consumption reliability and
safety, maintaining the power system stable operation as well as optimizing the
electric energy cost, the following solutions can be proposed:
limiting the energy consumption during the peak load periods and
shifting it onto the off load periods;
making long-term bilateral contracts on energy and power purchasing;
locating the low capacity sources (distributed generation) near the
consumers;
introducing energy saving technologies into goods and services
production.
The paper presents the analysis of the effect of energy consumption limitations
on the consumer’s profit in the short-term perspective. The loss function for
consumers can be expressed mathematically in different ways. The criterion
expressions for the energy consumption are defined provided the loss of profit is
minimum. The consumer sector is shown to have to be of a greater regulating
power in the electricity spot market operation.
Keywords: demand side management, competitive electricity market, limitation
of power consumption, peak hours, optimal value restrictions, specific damage,
schedule load.
