Assessment of the cost and environmental impact of demand side management on residential sector

The paper presents a detailed study of the potential impact on the cost and greenhouse gas emissions (GHG) through low voltage (LV) residential demand-side management (DSM). The proposed optimisation algorithm is used to shift non-critical residential loads, with the wet load category used as a case study, in order to minimise the total daily cost and emissions of GHG due to generation. This study shows that it is possible to reshape the total power demand and reduce the cost and emissions of demand to some extent. It is also shown that further optimisation of the cost leads to an increase in GHG emissions because of their conflicting nature.
