Title: Implementation of Demand Response Program in Residential Households (EU FP7 Project ‘Scalable Energy Management Infrastructure for Aggregation of Household’ SEMIAH)
Abstarct: Nowadays due to major technological, scientific and commercial breakthrough by developing an Information and Communication Technology (ICT) infrastructure, the demand side management can be implemented in specific sectors within the smart grid environment. Demand side management in the domestic sector can play an important role in reducing the peak demand on the power system network as well as facilitating integration of renewable energy resources. It can help in reducing stress and overloading within the distribution network and on power lines. In many countries, there are various demand response programs implemented for industrial and commercial sectors. There are very few demand response programs in use for energy management in residential sector using ICT technologies.
In this keynote speech, the learning from the EU FP7 project tilted ‘Scalable Energy Management Infrastructure for Aggregation of Household’ (SEMIAH) will be shared. The SEMIAH project has pursued the implementation of demand response using ICT infrastructure in residential households using centralized approach as virtual power plant. This infrastructure has enabled scheduling of selected power intensive selected residential loads’ operation to off-peak demand periods for reducing the expected peak demand on the electrical energy network. The SEMIAH project has used state-of-the-art approach using ICT infrastructure to support the deployment and modernisation of home energy management systems for demand side management. In this project, partners have contributed in developing a centralised energy management system for provisioning of demand response services based on aggregation, forecasting, and scheduling of electricity consumption in the residential sector. The SEMIAH concept has enabled aggregation of households connected to the system and acted through direct load control to shift or curtail specific power intensive electrical loads considering the flexibilities of the prosumers and the utility demand limits. The project has delivered a hardware solution that enables control of selected electrical load operation based on demand limits considering the renewable energy generation. To successfully implement SEMIAH, the project consortium has studied new business models for electricity players and residential customers to quantify costs and benefits for actors in the value chain. The SEMIAH system shall contribute to the benefit of residential customers, energy utilities, and the society in general through lowering electricity bills, and providing higher stability of the electricity grid. Hereby, the project will enable savings in CO2 emissions and fuel costs, as well as reducing investments in electricity network expansions and peak power plants.
