The EU goal of achieving carbon neutrality by 2050 will require profound changes in the electricity supply chain. In this context, Distribution System Operators (DSOs) are expected to adopt solutions to efficiently integrate distributed energy resources (DER), including the implementation of local flexibility mechanisms. Thus, DSOs would procure services from DER like distributed generation, demand response, or storage to support grid expansion, attain significant cost savings, and swifter DER integration. However, the use of flexibility mechanisms still faces barriers posed by national regulation. Regulatory sandboxes may be used to overcome this gap by enabling and supporting the development of local flexibility mechanisms. This paper performs an international review of four leading countries in the use of sandbox and flexibility, identifies best practices, and, based on the lessons learned, provides recommendations to implement local flexibility mechanisms for DSOs in Spain under regulatory sandboxes

This paper proposes a framework for predicting and mitigating insider collusion threat in relational database systems. The proposed model provides a robust technique for database architect and administrators to predict insider collusion threat when designing database schema or when granting privileges. Moreover, it proposes a real time monitoring technique that monitors the growing knowledgebases of insiders while executing transactions and the possible collusion insider attacks that may be launched based on insiders accesses and inferences. Furthermore, the paper proposes a mitigating technique based on the segregation of duties principle and the discovered collusion insider threat to mitigate the problem. The proposed model was tested to show its usefulness and applicability.

The stability and effectiveness of supply chain financing union are directly affected by income fluctuation and unequal distribution problems, subsequently making the economic interests of the involved parties impacted. In this paper, the incomes of the parties in the union were distributed using Shapley value from the perspective of cooperative game under the background of the supply chain financing based on third-party trading platform, and then correction factors were weighted by introducing risk correction factors and combining with analytic hierarchy process (AHP), in order to improve the original model. Finally, the feasibility of the scheme was proved using example.
