Proaktives Verteilnetz - Proactive Distribution Grid ETIP SNET Workshop Aachen, September 18-19 http://www.rwe.com/web/cms/mediablob/de/2878258/data/1/blob.jpg http://www.rwe.com/web/cms/mediablob/de/2878240/data/1/blob.jpg http://www.rwe.com/web/cms/mediablob/de/2878242/data/1/blob.jpg http://www.rwe.com/web/cms/mediablob/de/2878250/data/1/blob.jpg http://www.rwe.com/web/cms/mediablob/de/2878278/data/1/blob.jpg 18 -19.09.2017 SEITE 1 Das proaktive Verteilnetz
The majority of the new producers are connected to the distribution grids There is a global trend for DER, Germany is one of the main applications One of the key attributes of DER-generation is its volatility There is also a trend for increasing flexibility and demand on the demand side The usage of flexibility in supply&demand in distribution grids is necessary to guarantee a sustainable and reliable energy system Energiewende UHV HV MV LV 18 -19.09.2017 SEITE 2 Das proaktive Verteilnetz
Traffic light concepts enable synergies between a market- and grid-driven usage of flexibility Goals of the traffic light system Drivers Open up flexibility Resolving grid congestions Expand energy grids at optimal (system) costs in the long term Enhancing interaction of grid & market MORE CONSUMPTION HIGHER COINCIDENCE FLUCTUATING FEED-IN TODAY TOMORROW PROSPECTIVE The traffic light system is not The traffic light system is Indication of the actual status of grid <-> market interaction Indication of the actual grid condition or available grid capacity Market information of the actual usage of flexibility through DSOs Information on the acutal grid stability and security of supply 18 -19.09.2017 SEITE 3 Das proaktive Verteilnetz
A valuable flexibility concept needs to incorporate grid and market interests in a common manner market oriented use portfolio optimization of demand and supply system oriented use balancing independent of location Flexibility adaption of generation or demand behavior by external signals Customer oriented use self-consumption grid oriented use avoid local grid constraints 18 -19.09.2017 SEITE 4 Das proaktive Verteilnetz
Interaction of Market & Grid - Traffic light concept enables a flexible market environment Green Flexibility is offered by sales/ aggregators for market and system oriented portfolio optimisation and for balancing Yellow Flexibility is requested by DSO on a contractual basis to avoid economic inefficient network expansion Red Flexibility is controlled by DSO without contractual basis to preserve a secure network operation 18 -19.09.2017 SEITE 5 Das proaktive Verteilnetz
Target: Creating an operational grid <-> market interaction model within a demanding environment Optimize grid operation especially within areas of high DER-share to resolve network bottlenecks MARKET Design grid <-> market interactions within the orange regime Development of generic requirements for a mediating communication and service platform Develop and use flexibility for the distribution grid to minimize grid expansions GRID Deliver recommendations for a future market design 18 -19.09.2017 SEITE 6 Das proaktive Verteilnetz
