- The use of ground-sourced heat pumps as main heating systems has increased in Sweden in the last fifteen years to the point that it is the country with the highest amount of GSHP in Europe. Heat pumps are chosen by many households due to their economic savings value; In contrast, electricity prices in Sweden have almost doubled since 2006, threatening their economic benefits. It is therefore, essential to understand GSHPs impact on the user´s electricity consumption and provide suitable demand-response programs that could help develop a model capable of forecasting consumption and provide decision support information to make the best use of the technology. This paper analyses questionnaire surveys and consumption patterns were evaluated for 322 households with installed GSHPs and different pricing schemes in order to increase the understanding of mass use of this type of heating system.

Energy Demand Model Design for Forecasting Electricity Consumption and Simulating Demand Response Scenarios in Sweden
- 2012
-
Konferensbidrag (refereegranskat)abstract
- The introduction of a deregulated power system market and development of smart-metering technologies in Sweden, bring new opportunities for fully exploiting its power system efficiency and reliability, such as price-based demand response (DR) programs at a large scale for household, commercial and industrial users. The deployments of these DR programs require, however, very accurate demand forecasting models. The traditional approach of obtaining the total energy use and peak demand does not offer the required detailed information. This article reviews several methodologies for forecasting electricity consumption from a bottom-up perspective in order to define the required parameters and structure for obtaining an energy model. This model will finally include energy usage data, behavioural parameters obtained from a survey conducted with 5 000 end-users in different Swedish distribution system operators’ areas, and physical conditions for the facilities (internal/external temperatures and insulation materials). This information is provided from previous research studies performed at Mälardalen University and Swedish electric utilities companies. The obtained model should be able to adjust its parameters dynamically in order to simulate several demand-response scenarios based on four different strategies: time of use pricing, use of curtailable/interruptible rates, imposition of penalties for usage beyond predetermined levels, and real time pricing.

Large-Scale Energy Intervention Scenarios as a method investigating demand response potentials
- 2012
-
Konferensbidrag (refereegranskat)abstract
- It is often stated that electricity systems need further development in order to include the ambitious amount of renewable energy. Smart Grids are seen as an enabler for an electricity market with increased benefits for both consumers and environment. From a system level perspective, many advantages could be achieved by implementing these innovative technologies. Smart Grids are expected to be more flexible and could result in that expensive investments can be avoided. Furthermore, implementing smart metering could give consumers possibilities to obtain a better understanding of their own electricity consumption. The information could also help consumers to react on price signals by adjusting their consumption patterns. Increased knowledge usually increase awareness and could therefore be positive for energy efficiency activities.In order to investigate the potential for increased consumer participation in the electricity market with respect to demand-response and micro generation, a new evaluation method is proposed. In the project “Increased consumer power on the Nordic electricity market” large-scale energy intervention scenarios are being applied.The purpose of this it paper is to describe this methodology, its’ relation to other methods and the foreseen benefits to increase knowledge on the potential of demand-side participation in wider areas (e.g. cities and regions). In the experiment different social, economic and environmental incentives are evaluated in order to understand how they influence electricity consumption behaviour in the short term. The design of this new methodology is based on vast experiences of energy consumption surveys in residential consumer segment, feedback studies, focus groups and other consumer interaction methods.
