Abstract

Policy makers are formulating offshore energy infrastructure plans, including wind turbines, electrolyzers, and HVDC transmission lines. An effective market design is crucial to guide cost-efficient investments and dispatch decisions. This paper jointly studies the impact of offshore market design choices on the investment in offshore electrolyzers and HVDC transmission capacity. We present a bilevel model that incorporates investments in offshore energy infrastructure, day-ahead market dispatch, and potential redispatch actions near real-time to ensure transmission constraints are respected. Our findings demonstrate that full nodal pricing, i.e., nodal pricing both onshore and offshore, outperforms the onshore zonal combined with offshore nodal pricing or offshore zonal layouts. While combining onshore zonal with offshore nodal pricing can be considered as a second-best option, it generally diminishes the profitability of offshore wind farms. However, if investment costs of offshore electrolyzers are relatively low, they can serve as catalysts to increase the revenues of the offshore wind farms. This study contributes to the understanding of market designs for highly interconnected offshore power systems, offering insights into the impact of congestion pricing methodologies on investment decisions. Besides, it is useful towards understanding the interaction of offshore loads like electrolyzers with financial support mechanisms for offshore wind farms.

2. Prototyping the DOPTEST Framework for Simulation-Based Testing of System Integration Strategies in Districts

Abstract

This paper introduces the District Optimization Testing (DOPTEST) concept, which naturally extends from the Building Optimization Testing (BOPTEST) framework, for simulation-based testing of advanced control strategies in districts. While the focus of the BOPTEST framework is on individual building control, DOPTEST is meant to assess system integration strategies at a district level. This paper lays down the design requirements and modeling methodology for district emulators in DOPTEST and shows a simulation example of its first test case prototype.

Abstract

To avoid unnecessary distribution network investments, distribution tariffs are expected to become more cost-reflective, and DSOs are expected to procure flexibility. This will provide an implicit and an explicit incentive to provide demand-side flexibility. In this paper, we develop a long-term bi-level equilibrium model. In the upper level, the DSO optimizes social welfare by deciding the level of investment in the distribution network and/or curtailing consumers. The regulated DSO also sets a network tariff to recover the network and flexibility costs. In the lower level, the consumers, active and passive, maximize their own welfare. We find that implicit and explicit incentives for demand-side flexibility are complementary regulatory tools, but there are limits. If network tariffs are too imperfect, the resulting consumption profiles can become too expensive to fix with curtailment. We also find that it is difficult to set an appropriate level of compensation because of the reaction by prosumers.

INTRODUCTION The Clean Energy Package (CEP) Directive (EU) 2019/944 calls on the Member States to develop regulatory frameworks that incentivize distribution system operators (DSOs) to consider the use of [...]
