Abstract In order to use loads in an active andintelligent way to resolve technical problems in thenetworks or contribute to ancillary services (smart

grid), this paper presents a new method of air-

conditioning control that allows to reduce the peak

consumption by maintaining thermal comforts. This

control is based on the variable set-point temperature

of air conditioning adapted to the permissible power.

This power can be fixed by outdoor signal from DNO

(Distribution Network Operators). The proposed air-

conditioning control is tested by simulation under

EMTP-RV with satisfied results for a distribution

network containing air-conditioners. Different factors

such as: weather conditions, the thermal parametersof buildings and other residential loads (lighting,

freezer, refrigerator, cooker, washing-machine )are taken into account.

These results show that the proposed solution can be

efficiently applied for a group of loads, buildings

(such as a virtual consumer) in distribution networks

in order to reduce the peak consumption in the

distribution network.

Index Terms- Air conditioning, direct load control,

adaptive control, peak load reduction, distribution

network.
