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


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.

IntroductionMatthias Stifter, René Kamphuis

Block 1: Theoretical foundations and simulations

Roman Targosz (Copper Alliance Europe) – Mapping Flexibility of Power Systems

Copper Alliance and Ecofys have been involved in a joint study on flexibility in power systems. A new overview clarifies the flexibility needs for the transition to power systems with very high penetration levels of variable renewable energy sources (VRES). The talk provides a comprehensive assessment of the complete spectrum of flexibility options and identifies key barriers for their deployment.

Matthias Gallus (Swiss Federal Office of Energy SFOE) – DSM in Switzerland – Possible Coordination of Networks and Markets

The coordination of flexibility (load, production, storage) for markets and networks at the same time is a complex task. Switzerland is looking into solutions, which offer a large playing field for markets and competition. Of interest are topics such as benefits for markets, networks and total social welfare, dynamic innovation, data exchange, processes for markets and non-discriminatory access.

Tara Esterl (AIT Austrian Institute of Technology) – Load Flexibility in small and medium enterprises and criteria for successfully enabling them

In the project hybrid-VPP4DSO DR-components in Austria and Slovenia are studied regarding their flexibility potential and their willingness to provide their flexibility. Potential business models and business cases are investigated to make use of this flexibility in different markets. Furthermore, the impact on the grids is analyzed and how this flexibility can relieve the grids in critical situations. Hybrid solutions – serving both markets and grids – are challenging regarding unbundling requirements, but have the highest priority of the project.

Stephen Galsworthy (TNO Netherlands Organisation for Applied Scientific Research) – Valuing Flexibility in power systems: the ValueFlex project

The VALUEFLEX project aims at developing services able to give to utilities and grid operators a better understanding of the value of electricity flexibility. These services are based on a comprehensive set of simulation tooling (the Toolbox) that allows companies to analyse the economic and technical feasibility of demand response services.

Steve Widergren (PNNL, USA) – Buildings Equipment Connectivity Interoperability for Energy Applications

Buildings automation can become a major contributor for providing flexibility services to the electric grid and greater overall energy efficiency, but the vast majority of facilities (at least in the USA) are not prepared to easily coordinate with the grid even if an flexibility signal was available. Efforts are underway to advance interoperability of connected building equipment to bring down integration costs and enable buildings to be more efficient and flexible users of energy.

Block 2: Realized Demand Response

Arnoud Rijnevald (Stedin) and Marijn Renting (Enexis, the Netherlands) – Field test verified flexibility options from a DSM perspective

Flexibility is an upcoming theme for DSOs. Some insights and first results of current test beds, of the Dutch DSOs Stedin and Enexis, which explore demand side management will be shared. Also, questions that still need to be answered in the Netherlands regarding DSM by DSOs, will be addressed.

Elke Klaassen (Enexis, the Netherlands) – Flexibility and Cost Benefit Analysis of the PowerMatchingCity-II Living Lab in Hoogkerk the Netherlands

Based on the results of the Dutch smart grid pilot PowerMatching City phase-II (45 house holds), we try to answer the question: what are the potential benefits of a large-scale implementation of PowerMatching City phase-II in the Netherlands? To do so, the measured data from the pilot was used to quantify the flexibility of the smart appliances (i.e. micro-CHPs, heat pumps and electric vehicles). Consequently, this flexibility is used as input for a model that represents the Dutch power system. To quantify the benefits both the energy market value and the grid value are assessed, using basic energy market simulations and load balance calculations respectively.

Daniel Brodén (KTH Royal Institute of Technology) – Demand response in the Smart Grid Gotland project

This talk presents preliminary results and studies from the Smart Grid Gotland Project. The focus of the talk is on subproject (i) wind power integration and (ii) market test and installation. Results from subproject (i) include simulation results on demand-response potential for congestion management. Results from subproject (ii) include lessons learned from an actual demand-response implementation and survey results on customer satisfaction.

Matthias Stifter (Austrian Institute of Technology) – Flexibility analysis and implications of the real time market concept of EcoGrid

One of the possible approaches to implement demand response is using a real-time market. Within the EcoGrid project, a real-time market place for distributed energy resources was implemented in a demonstration on the island of Bornholm in Denmark with considerable customer involvement. Flexibility and volume of demand response activated by real-time price signals will be discussed.

Werner Friedl (Austrian Institute of Technology) – Regulatory Recommendations of the Deployment of Flexibility

The report “Regulatory Recommendations for the Deployment of Flexibility“ focuses on flexibility from distributed resources, including demand side participation, and seeks to identify flexibility services, relevant value chains, but also the necessary commercial and market arrangements, while it answers the question on how different actors can be incentivised to provide and use flexibility. Finally, concrete recommendations are provided to the European Commission, to policy makers and stakeholders, for removing regulatory barriers and incentivising the uptake of flexibility from distributed resources.
