To handle the local effects of new RGs on the distribution grid, the more efficient utilization of distributed local flexibility (LF) resources is necessary. However, the optimal market design is not yet known for LF products. This paper investigates a novel cost allocation mechanism in the context of this market challenge. The mechanism is designed to provide several important advantages of peer-to-peer trading without creating barriers to practical application. It provides partial disintermediation. The acquisition of LF remains the responsibility of the DSO, while the financial costs of the transaction are covered on power exchanges (PXs). To provide this functionality, the clearing algorithm of the PX in question has to incorporate a novel feature we call the Payment Redistribution Technique. This technique allows the buyers’ expenses to be larger than the sellers’ income, and the difference is used to finance flexibility costs. Its mathematical formulation is presented and analyzed in detail, considering computational efficiency and accuracy. Afterward, a realistic case study is constructed to demonstrate the operation of the algorithm and its energy market effects.}, year = {2022}, eissn = {1996-1073} } @inproceedings{MTMT:33067588, title = {Feasibility study of a local peer-to-peer energy market: Implications on a real-life LV distribution grid}, url = {https://m2.mtmt.hu/api/publication/33067588}, author = {Sütő, Bence and Sinkovics, Bálint and Táczi, István and Barancsuk, Lilla and Polgári, Beáta and Sőrés, Péter Márk and Hartmann, Bálint and Divényi, Dániel and Vokony, István and Csercsik, Dávid}, booktitle = {2022 8th International Youth Conference on Energy (IYCE)}, doi = {10.1109/IYCE54153.2022.9857520}, unique-id = {33067588}, abstract = {The H2020 INTERRFACE project designs, develops, and exploits an Interoperable pan-European Grid Services Architecture to act as the interface between the power system (TSO and DSO) and the customers and allow the seamless and coordinated operation of all stakeholders to use and procure common services.

Abstract In order to enhance the liquidity and stability of ancillary service markets in Europe and to motivate the participation of renewable energy resources, the incorporation of control reserve procurement into day-ahead power exchanges (PXs) is proposed. The design of the corresponding clearing algorithm is presented in detail. The model allows the submission of combined energy-reserve orders and guarantees that opportunity costs of power producers are taken into account. It can also handle non-convex offers (e.g. block bids) and market coupling that are essential components of European PX designs. The formulated optimization problem can be classified as a convex Mixed Integer Quadratic Program; consequently, its solution can be found using readily available generic solvers. A numerical simulation is executed for the purpose of demonstration and also to make a comparison between joint and separated allocation of energy and reserves. The simple initial analysis suggests that the proposed integration approach is beneficial.}, year = {2019}, eissn = {1879-3517}, pages = {269-285} }
