Capacity Assessment of Residential Demand Response Mechanisms

The power system design was mainly based on developing the supply side (supply follows the demand) and minor attention was given in controlling the demand side. During the effort to accommodate larger shares of renewable energy sources, while maintaining the power balance and ensuring the reliability of the power system, the implementation of demand response mechanisms may provide considerable options to reshape the supply of electrical energy. This study presents a new approach for modelling flexible loads and aims to create further knowledge on the potentials of residential demand response concepts. Specific types of loads were modelled as finite states machines, based on behavioural and technical constraints. Then, the available capacity for demand response actions was quantified based on Monte Carlo simulations, and normalised aggregate load profiles are provided for electric vehicles and four typical domestic appliances.
