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.
