Abstract
In light of the advancing energy transition and an increasing amount of intermittent renewable energy to be integrated, flexibility from distributed energy resources will be key. In this paper, the Italian UVAM (Unità Virtuali Abilitate Miste, i.e., virtually aggregated mixed units) project, one of the biggest pilots in Europe to serve this purpose, is critically reviewed and mapped after two years of operation. The pilot is analyzed on a global level as well as the individual participant level. Based on the extensive analysis of actual market data, different strategies of participating companies to obtain capacity in accordance with the pilot project’s design are identified. Furthermore, the specific bidding strategies of individual participating units on the balancing market are outlined. Alongside this, the overall pilot project’s market integration, in terms of offered and accepted bids, is depicted. The thorough data analysis, therefore, serves as an input and fundamental building block for future electricity market modeling. Comprehending specific data from the coronavirus disease 2019 (COVID-19) pandemic, provides insights for future high renewable-energy scenarios. Based on the analysis findings, valuable deliverables are devised for both policy-makers and decision-makers who aim to leverage the flexibility potential of distributed resources.
Highlights
In order to evaluate the outcomes of the ongoing UVAM project and analyze its effectiveness in terms of improving the integration of virtual aggregated units and aggregators in general in the Ancillary Service Markets (ASM), a methodology for the analysis of public data is described in the following
Since UVAMs can participate in both ASMs, the amount of offered/accepted quantity is computed as the sum of the two individual results for each hour
Only relies on publicly available raw market data, it is possible to obtain some essential which only relies on publicly available raw market data, it is possible to obtain some esinsights into the actual operation of aggregators on the ASM, fulfilling the double objective sential insights into the actual operation of aggregators on offers the ASM, the double of surveying overall market outcomes concerning and,fulfilling most notably, monobjective of surveying overall market outcomes concerning offers and, most notaitoring their individual performance in the market
Summary
By aiming for a significant reduction of greenhouse gas emissions, the signing parties of the Paris Climate Agreement have laid the contractual foundation for decarbonizing our society. Based on the national commitments towards the “well below 2 ◦ C” target, the signing parties formulated measures to reach the envisaged global CO2 emission reduction and to corroborate the first climate agreement on a fully global scale. Together with the Clean Energy Package (CEP), the first national energy and climate plans were introduced on a pan-European level. The latter defined for the first time legally binding targets, for 2030 a 40% greenhouse gas emissions reduction relative to 1990, an overall renewable energy share of 32% and an interconnection target for electricity markets of 15% [1]
