Integrid - Bridging the Gap

43 The HLUC12 has different types of KPIs, some for continuous monitoring and others for flexibility requests and activations. The results show that both metering reading index and flexibility forecast algorithms have consistent results throughout the demonstration period, proving the reliability of the metering technology and VPP built-in forecast algorithms. The results relating to the economic performance of the VPP technology in the Portuguese demo are highly dependent on the regulatory framework and the number of flexibility requests and successful activations. As the selected Portuguese network is relatively reliable, there are not a great number of constrains that need to resort to flexibility in order to solve them, thus limiting the possible number of activation requests for flexibility on that network, directly impacting on the economical KPIs of the VPP in the Portuguese demo. Overall insights into the demonstration Results achieved in the InteGrid project are clear and show that an effective operational grid management strategy supported by flexibility and active participation by the client can improve the quality and continuity of service, mainly when applied to grids with high RES and EV penetration. It may not be possible to address all problems such as voltage violations, overloads mainly due to the position in the feeder, of flexible controlled assets in the node where the violation exists. Two key aspects were identified in the project. Firstly, the importance of simplified architecture for data management capabilities that can compute-heavy data sets, and secondly, the most relevant aspect, keeping clients engaged making them the most relevant actor in the ecosystem so developed. DSO architectures should be able to integrate requests coming from both low voltage customers, industrial and generation facilities, and aggregators into an open ecosystem. All these actors are key enablers to run such disruptive transformation projects. With regard to the IT infrastructure, as was concluded in InteGrid, it is very important that IT developers can integrate different architecture. A successful model was developed and connected, including high-tech solutions such as Sap Cloud, the Cybergrid Virtual Table 4.14 - HLUC12 KPIs and Description KPI Result Description Meter reading success index 96.77% (average) This KPI captures the total amount of communication attempts within the allowed time frame and indicates the efficiency of the communication by revealing the portion of successful communication. Commercial VPP (mFRR or RR) - Economic Parameters -61,144.00€ This KPI evaluates the benefits and performance of the commercial VPP (in the mFRR market or RR) from an economic point of view. The KPI compares the cash flow from revenues from mFRR or RR market participation with the costs for VPP operation and the reimbursement of the DER and controllable resources within one or two years of operation. KP4 Critical Volume of Commercial VPP 8 MW This KPI indicates the required amount of tradeable flexibility in order to reach the economic break even point after 1 year (or 2 years) Required amount of total flexible capacity available for remote control 5.3 Describes the amount of flexibility from all types of DER necessary to provide the required service for the mFRR market throughout the whole service period without harming any threshold values for grid stability. Differentiates between upward and downward. Forecasting accuracy 97.4% (average) This KPI is used to evaluate the accuracy of the forecasting algorithms for load and generation on a pool level. This is a measure of the reliability of the applied forecasting method and takes into consideration the considered forecast horizon. Annual service costs of the technical VPP 72,263.00€ This KPI addresses the question of the price at which the tVPP service can be offered to a DSO. It differentiates between the costs of the VPP system and VPP operator and the costs to reimburse DER owners. The following calculation for KPI-7 was used.
