Integrid - Bridging the Gap

49 H12K05ELubCG, the DSO perspective: The objective of this KPI is to evaluate the benefits and performance of the technical VPP (DSO support) from an economic point of view by comparing the costs of the service provided by a technical VPP with the capital costs of (the alternative) a new grid investment over a period of five years (or 10 years). Is the investment in the technical VPP economical from a DSO’s perspective? Currently, Elektro Ljubljana is not in a position to use the flexible active power of grid users to solve grid problems. Legislation which would enable such an approach under the services developed by InteGrid is still being prepared. This aside, 7 MW of flexibility can be used for supporting grid operation. The DSO had analysed how much energy could be provided through this 7 MWof flexible power and the result was 851.8 MWh/year in 2020. This is the best estimate scenario. Costs of the tVPP services were calculated at 200 EUR/MWh = 170,362 EUR /year and net savings for the DSO were 577,638 EUR/year. The technical VPP is an economically acceptable investment for the DSO. SWEDISH DEMONSTRATOR The Stockholm demonstrator, Figure 4.25 emphasised user engagement mechanisms, employing novel approaches and evaluation methods to overcome the household engagement barrier associated with demand side management programs. In addition to demand side management programs, grid-side solutions such as forecasting signals and smart substations were deployed and evaluated in Stockholm. Demonstrator sites and solutions and their corresponding cases of use are listed in Table 4.18. Consumer Demo sites Stockholm Royal Seaport StockholmRoyal Seaport (SRS) is an eco-district under construction in Stockholm. The district is designed with the ambition of becoming a world-class environmental urban district with targets to reduce carbon dioxide emissions by one-third of the current Swedish per capita by 2020, and become completely fossil fuel-free by 2030 – 20 years ahead of Stockholm city’s environmental ambitions (visionsrs2030, 2010) 2 . To achieve these targets, the sustainable urban district is reliant on advance ICT and urban metabolism to monitor its sustainability performance (City of Stockholm, 2010). Still under construction, the SRS has planned to build 12,000 new dwellings and 35,000 workspaces by 2030. The HLUC 11, Active House (PUC01.11), is a residential demand response intervention program taking place in the Stockholm Royal Seaport district. The test site includes 154 highly sub-metered and automated apartments (see Figure 4.26) where the main engagements are feedback, automation and comfort for residents. The apartments mainly rely upon Home Energy Management Systems (HEMS) and Smart Appliances to provide smart home features such as energy feedback, control and monitoring — making it an ideal testing site for demand side management programs such as Active house.
