2.1.1. Reducible Loads

The meaning of reducible loads is that the power dispatch center can interrupt the load without affecting user comfort. Typical load reductions include air conditioning loads and lighting. Its mathematical model can be expressed as follows:

$$
\Delta P\_{\rm re}(t) = f\_1(P\_0(t), \Delta p\_{\rm re}, k\_{\rm re}(t), \upsilon\_{\rm re}(t)) \tag{2}
$$

where <sup>Δ</sup>*P*re(*t*) is the response of the load during the *t* period; Δ*p*re is the change of the electricity price in the t period; *k*re(*t*) is the self-elastic coefficient of the load in the t period; and *<sup>v</sup>*re(*t*) is the rate of the load reduction.
