1 1 Smart control of multiple energy commodities on district scale Frans Koene Sustainable places, Nice, 1-3 Oct 2014

2 2 Partners

3 3 How can we match energy supply and demand? -Energy storage -Smart control of appliances→ time shift of demand Challenge Facilitate the implementation of large shares of renewables in energy supply systems Daily mismatch Annual mismatch

4 4 Business models based on flexibility of demand Control algorithm to match supply & demand of heat and electricity Simulation environment Simulation Engine Models of components boiler CHP GUI storage PV Dynamic aggregated model of buildings in the district Electricity and DHW profiles

5 Aggregated building model Inputs building model –Size, volume, windows, orientation –Thermal insulation –Thermal set points for heating & cooling –Internal heat generation –Parameters automatic solar shading = F.G.H.

8 8 Business Concepts based on flexibility CaseBuyer of flexibilityObjective 1Prosumers (aggregated) reduce energy bill (buy at low prices) 5 Transmission System Operator (TSO) reduce imbalance on national level 2Energy retailer / BRP maximise the margin between purchases and sales of energy 3 Balancing Responsible Party (BRP) reduce imbalance in portfolio 4 Distribution System Operator (DSO) peak shaving (avoiding capacity problems)

9 9 Case studies Tweewaters (BE) Supply: CHP (heat + electricity) + peak boilers (heat) + market (electricity) + DH Demand: residential consumers (heat + electricity) + market (electricity) Flexibility: CHP + smart appliances Houthaven (NL) Supply: HPs, PV, waste heat (incineration plant), ground source cold storage,…+ DHC Demand: low energy buildings - residential + commercial/ public buildings Potentially demand response (smart appliances, pumps) Bergamo (IT) Existing energy concept: DH + heat storage – shutdown of CHP Energy vision: different alternatives for heat production (centralized boiler, biomass..), PV (46 kW p ) Demand: Residential buildings + commercial/ public buildings Freiburg (GE) Supply: CHPs + boilers, centralized heat storage + DH Demand: residential buildings + commercial/ public buildings Dalian (CN) Supply: CHP + peak boiler (heat) + sewage source / seawater source HP (heat/cold) + solar collectors + DH Demand: residential consumers + industrial use (heat + electricity + cold)

10 10 1.Reference or BAU scenario - conventional sources for energy supply - electricity from the public grid - heat produced by de-central gas fired boilers. 2.RES (Renewable Energy Sources) or green scenario with fixed energy demand - heat and electricity are (partly) produced with renewables (PV, biomas CHP) - no demand-side flexibility (i.e. no smart appliances) 3.Smart scenario or RES scenario with flexible energy demand and supply - renewable energy sources (as in 2 nd scenario) - demand-side flexibility - business objective: local balancing and national balancing Scenarios

11  201.300 m 2 residential  13.900 m 2 commercial  14 aggregated buildings  16.8 km heat network  Copper plate grid  No cold network (electrical cooling)  Rooftop & District PV (4.5 kW p ) Example: district of Houthaven, Amsterdam

12 12 Space heating– RES scenario

13 13 Space heating– smart scenario

14 14 Space cooling – RES scenario

15 15 Energy bill for cooling reduced by 36% Space cooling – smart scenario

16 16 Results (preliminary)

17  Results are incomplete and preliminary  Net energy demand does not vary much between 3 scenarios  Increase of %RES in smart scenario depends on amount of flexibility  Depending on business case, benefits from smart scenario may be lower energy bill, peak shaving etc. Future work using the simulation platform:  Effect of smart (predictive) agents  Use of electrical storage, i.e. electric vehicles 17 Conclusions
