“…Examples of such contracts would be where renewable power producers bid in the day ahead market but also buy options from natural gas producers (reliable sources) to hedge their risks in case of lower than anticipated production. 38 , 39 The forward contract example in our study is essentially a pre-bid power delivery promise (corresponding to the threshold) and the energy droughts are the periods where the producer will not be able to meet their obligations.…”

“…The setting up of reliability contracts between conventional generators and VRE generators to avoid unexpected energy deficits due to variability in generation is proposed in [70,71]. In the proposed work, wind generators are penalized for not meeting their obligations for providing power as per their estimated offer in a day-ahead electricity market.…”

Global electricity markets are undergoing a rapid transformation in their energy mix to meet commitments towards sustainable electric grids. This change in energy mix engenders significant challenges, specifically concerning the management of non-dispatchable energy resources. System and market operators are required to meet power system security and reliability requirements whilst providing electricity at competitive prices. An overview of electricity markets is provided in this paper with a critical appraisal of each market’s ability to manage the large-scale energy mix transition. This paper provides a commentary on the distinct features of electricity market models implemented around the world and highlights the barriers within these market models that are hindering the energy mix transition. Various researchers and policymakers are proposing solutions and market reforms for the smooth transitioning of the energy mix. This paper presents a systematic review of the proposed solutions in the literature and critiques the effectiveness and ease of implementation of the reviewed solutions. Research gaps and future research directions are indicated to promote further exploration towards the effective integration of large-scale renewable energy technologies.

“…It is now imperative to develop advanced control methodologies that can enable wind power plants [8], [10], [13] and other RERs [5] to provide ancillary services in order to enhance power grid stability. At the same time, the electricity markets have to be restructured so at to promote optimal operation of power grids with renewables [15], [18], [21].…”

Operating modern power grids with stability guarantees is admittedly imperative. Classic stability methods are not well-suited for these dynamic systems as they involve centralized gathering of information and computation of the system's eigenvalues, processes which are oftentimes not privacy-preserving and computationally burdensome. System operators (SOs) would nowadays have to be able to quickly and efficiently assess smallsignal stability as the power grid operating conditions change more dynamically while also respect the privacy of the distributed energy resources (DERs). Motivated by all these, in this paper we introduce a framework that comprises a computationally efficient, privacy preserving, distributed and compositional stability assessment method. Our proposed method first calls for representative agents at various buses to exchange information with their neighbors and design their local controls in order to meet some local stability conditions. Following that, the agents are required to notify the SO whether their local conditions are satisfied or not. In case the agents cannot verify their local conditions they can augment their local controls using a global control input. The SO can then warrant stability of the interconnected power grid by assembling the local stability guarantees, established by the agents, in a compositional manner. We analytically derive the local stability conditions and prove that when they are collectively satisfied stability of the interconnected system ensues. We illustrate the effectiveness of our proposed DSA method via a numerical example centered around a three-bus power grid.
