Energy services bridging the gap between residential flexibility and energy markets

Abstract

This article addresses the developments ongoing in SENSIBLE, an H2020 funded project focused on energy storage and energy management, which demonstration occurs in Évora-Portugal, Nottingham-UK and Nuremberg-Germany. Currently presented work focus the concepts and developments necessary in order to make possible that residential clients can participate in a market environment with their electrical flexibility, also considering Distribution System Operator (DSO) needs when gird is under stress caused by any technical constraint. Moreover than the concept behind it is necessary to consider several developments: i) a low layer where residential assets will live in customers houses; ii) a high-level layers where market tools and DSO management tools will live; iii) an intermediate layer which bridge the gap between the low layer and high layer. These developments are a result of the ongoing works under one of SENSIBLE use cases which demonstrations occurs in a small village in Évora district in Portugal.

Residential electrical and thermal storage optimisation in a market environment

“…It is important to mention that the term including R and C in equation (6) represents the energy dissipation in the EWH as a measure of energy loss, as proposed in [3]. All variable limits are shown in constraints (9)-(16).…”

“…The work presented here was performed within the frame of the EU Horizon 2020 project SENSIBLE (Storage Enabled Sustainable Energy for Buildings and Communities) [5]. The SENSIBLE use case "Flexibility and demand side Paper 1086 CIRED 2017 2/5 management in market participation" [6], assumes a retailer, or other energy service company, which aggregates a number of customers and participates in a market in order to optimize its electricity costs and add value to the flexibilities that customers can offer.…”

“…To reflect a more realistic analysis, we forecast the households' load behaviour using data from the residential energy management equipment in SENSIBLE's Evora real world demonstrator [6,7].…”

Low-voltage grid upgrades enabling islanding operation

“…SMs able to provide DSM schemes than can request additional flexibility from clients, based on a residential home energy management system able to manage residential storage, residential PV generation and residential flexible loads, in case of any technical constraint in distribution grid [4]. This flexibility will be requested my high-level tools in case of urgent constraints.…”

“…4). This residential flexibility is activated by DSO through each SM and managed locally by the HEMS system, which will control the PV, residential storage and controllable loads like water heaters to change its power flow with the LV network [4]. Fig.…”
