Task 17 - Integration of Demand Side Management, Energy Efficiency, Distributed Generation and Renewable Energy Sources

Synopsis | Motivation | Objectives and Approach | Participation | Contacts | Links | Phase 3 | Events Phase 1 | Events Phase 2 | Events Phase 3 | Publications


As countries implement energy policies that promote energy efficiency, distributed generation and renewable energy resources, the share of distributed energy increases, particularly the intermittent type such as wind, solar, small hydro and combined heat and power (small and micro-CHP). Due to the fact that intermittent types of electricity generation are difficult to predict, electrical networks— both local and transmission— are turning to integrated distributed energy resource.

By combining distributed generation with energy storage and demand response,countries can decrease problems caused by distributed generation and increase the value of intermittent energy in the market.

The main objective of the Task is to study how to achieve the optimal integration of distributed generation, energy storages and flexible demand, and thus increase the value of distributed generation and demand response and decrease problems caused by intermittent distributed generation (mainly based on RES) in the physical electricity systems and at the electricity market. The Task deals with distributed energy resources both at local (distribution network and customer) level and at transmission system level where large wind farms are connected.

The first Phase of the Task was finished with seven participating countries in 2008 producing the state-of the art of the integration and proposal for the further studies.

On the basis of the Phase one the Task extension was started in 2010 with the main topics to assess the effects of the penetration of emerging DER technologies to different stakeholders and to the whole electricity system. Five countries participated in the Phase two and it finished in November 2012.

Phase three of the Task has started in May 2014.


Energy policies are promoting distributed energy resources such as energy efficiency, distributed generation (DG), energy storage devices, and renewable energy resources (RES), increasing the number of DG installations and especially variable output (only partly controllable) sources like wind power, solar, small hydro and combined heat and power.

Intermittent generation like wind can cause problems in grids, in physical balances and in adequacy of power.

Thus, there are two goals for integrating distributed energy resources locally and globally: network management point of view and energy market objectives.

Solutions to decrease the problems caused by the variable output of intermittent resources are to add energy storages into the system, create more flexibility on the supply side to mitigate supply intermittency and load variation, and to increase flexibility in electricity consumption. Combining the different characteristics of these resources is essential in increasing the value of distributed energy resources in the bulk power system and in the energy market.

This Task is focusing on the aspects of this integration.

Objectives and Approach

The main objective of this Task is to study how to achieve a better integration of flexible demand (Demand Response, Demand Side Management) with Distributed Generation, energy storages and Smart Grids. This would lead to an increase of the value of Demand Response, Demand Side Management and Distributed Generation and a decrease of problems caused by intermittent distributed generation (mainly based on renewable energy sources) in the physical electricity systems and at the electricity market.

Thus the integration means in this connection

-        how to optimally integrate and combine Demand Response and Energy Efficiency technologies  with Distributed Generation, Storage and Smart Grids technologies, at different network levels (low, medium and high voltage)

-        and how to combine the above mentioned technologies to ideally support the electricity networks and electricity market

The Task will provide the integration based solutions and examples on successful best practices to the problems defined above to the different stakeholders.

The first step in the Task was to carry out a scope study collecting information from the existing IEA Agreements, participating countries with the help of country experts and from organized workshops and other sources (research programs, field experience etc), analyzing the information on the basis of the above mentioned objectives and synthesizing the information to define the more detailed needs for the further work. The main output of the first step was this state-of-the art report and the proposal for the future work to be carried out as a second step of the Task.

On the basis of the Phase one the Task extension was started in 2010 with  the main topics  to assess the effects of the penetration of emerging DER technologies to different stakeholders and to the whole electricity system. The emerging DER technologies to be discussed include

-        plug-in electric and hybrid electric vehicles (PEV/PHEV)

-        different types of heatpumps for heating and cooling

-        photovoltaic at customer premises

-        micro-CHP at customer premises

-        energy storages (thermal/electricity) in the connection of previous technologies

-        smart metering

-        emerging ICT

-        Other technologies seen feasible in 10 – 20 years period, especially by 2020.

Phase 3

--> Link to Task Definition Dokument

Phase 3 of IEA-DSM Task 17 will address the current role and potential of flexibility in electricity demand and supply of systems of energy consuming/producing processes in buildings (residential, commercial and industrial) equipped with DER (Electric Vehicles, PV, storage, heat pumps, ...) and their impacts on the grid and markets. The interdependence between the physical infrastructure of grid and the market side will also be looked upon. The scalability and applicability of conducted and ongoing projects with respect to specific regional differences and requirements will be explored.

Renewable energy resources are increasingly integrated in distribution grids and increasingly pose challenges in keeping the market and the grid balanced at any moment in time. The aim of this task is the exchange of experiences and developments in the field of this embedding, focusing on distributed and dispersed renewable energy generation resources and flexible demand in homes and buildings. Technologies like PV systems, smart electric vehicle (EV) charging and discharging, optimization of electricity storage and of operations of heat pumps and (micro)-CHP, in earlier phases explored from a technological point of view, will be considered in relation to energy management systems and energy services. Furthermore, utilization of the smart metering infrastructure is considered as a enabler/provider of dynamic and real-time tariffs. The smart meter allows taking small consumers out of standard profiles that currently socialize market effects to one aggregated profile for a large number of customers instead of to individual profiles allowing much stronger incentives for demand response than current tariff schemes. These smart meter based allocation and short term reconciliation schemes expose small customers directly to the electricity market and reward them for their flexibility. In task 17, existing experiences of pilot projects which combine these aspects will be analyzed and discussed. The application and realization of successful projects in participating countries with respect to the specific regional differences and requirements are in focus.

Subtask 10: Potentials of Flexible Prosumers

This Subtask will compile and evaluate the concepts and implementation of automated customer and home/building energy management systems (CEMS/HEMS):

-       Controllability requirements

-       Opportunities, challenges and barriers

-       Energy and power balancing potentials

-       Smart technologies: Smart Meter, CEMS, Virtual Power Plants, distributed generation and electrical storage, heat pumps

-       The impact of these developments on existing metering, trade and billing processes

Subtask 11: Impact on stakeholder

The introduction of DER into competitive energy markets and 'fit-and-forget'-based distributions systems has non expected effects. Information from various sources will be analysed. A framework and a methodology will be developed for assessing impact on

-       Grid, market and prosumers operation

-       Sharing common benefits/losses

-       Societal optimization potential

-       Regulatory and legislative requirements

-       Comparison costs vs. delayed investments

Subtask 12 - Sharing experiences

Based on the results of collected pilots and case studies from the previous subtasks the results and findings of the finished projects in term of successful implementations, barriers and effectiveness will be analysed:

-       Collection of data / Workshops

-       Extrapolation from previously collected projects and applicability 

Subtask 13: Conclusion and Recommendation

Recommendations will be based on the experts’ opinion and will provide a ranking based on impacts, costs and likely future penetration.
