3.2.4. Active Loads

Due to a significant impact on the network's load profile, heavy industrial loads can also be a member of the DRA. Optimized operation of these resources allows them to provide a load levelling service. The peak demand can be shifted to the valley within the set limits (Equation (8)). The assumed constraint (Equation (9)) states that the sum of energy imported by the active load (AL) during the day period has to be equal to the daily electricity consumption, while the load remains passive.

$$\forall a \in A, \; \forall t \in T: 0.8 \cdot E^t\_{L.a} \le E^t\_{AL.a} \le 1.1 \cdot E^t\_{L.a} \tag{8}$$

$$\forall a \in A: \sum\_{t=1}^{T} E\_{AL,a}^{t} = \sum\_{t=1}^{T} E\_{L,a}^{t} \tag{9}$$
