EXECUTIVE SUMMARY – Summary and conclusionsTASK XVII: INTEGRATION OF DEMAND SIDE MANAGEMENT, DISTRIBUTEDGENERATION, RENEWABLE ENERGY SOURCES AND ENERGY STORAGESTask extension: The effects of the penetration of emerging DER technologies to differentstakeholders and to the whole electricity systemBackgroundObjectivesEnergy policies are promoting distributed energy resources such as energyefficiency, distributed generation (DG), energy storage devices, andrenewable energy resources (RES), increasing the number of DGinstallations 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 physicalbalances and in adequacy of power.Thus, there are two goals for integrating distributed energy resourceslocally and globally: network management point of view and energy marketobjectives.Solutions to decrease the problems caused by the variable output ofintermittent resources are to add energy storages into the system, createmore flexibility on the supply side to mitigate supply intermittency and loadvariation, and to increase flexibility in electricity consumption. Combiningthe different characteristics of these resources is essential in increasingthe value of distributed energy resources in the bulk power system and inthe energy market.This Task is focusing on the aspects of this integration.The main objective of this Task is to study how to achieve a betterintegration of flexible demand (Demand Response, Demand SideManagement) with Distributed Generation, energy storages and SmartGrids. This would lead to an increase of the value of Demand Response,Demand Side Management and Distributed Generation and a decrease ofproblems caused by intermittent distributed generation (mainly based onrenewable energy sources) in the physical electricity systems and at the
