The impact of the air conditioning load on the economy of electric power systems

This paper addresses the energy efficient technologies as applied to power system economy, together with their direct impact on the environment. It deals with the simulation of the daily load curve of electric power networks in the presence of an air conditioning load, taking into account the power system´s peak load, its load factor, the magnitude and the starting time point of the A/C load as well as its duration. If combined with an assumed fuel characteristic of the power network, the daily fuel consumption cost can be obtained. By means of a detailed parameter study on a sample power system, the impact of the air conditioning load component on the system´s daily cost is illustrated and discussed. Moreover, the economic feasibility of applying two suggested control strategies of the air-conditioning load aiming at reducing the system´s fuel consumption, is investigated
