Economically efficient design of market for system services under the web-of-cells architecture

Significant power sector developments beyond 2020 will require changing our approach towards electricity balancing paradigms and architectures. Presently, new electricity balancing concepts are being developed. Implementation of these in practice will depend on their timeliness, consistency and adaptability to the market. With the purpose of tailoring the concepts to practice, the development of a balancing market is of crucial importance. This article deals with this issue. It aims at developing of a high-level economically efficient market design for the procurement of system balancing products within the Web-of-Cells architecture. Literature and comparative analysis methods are applied to implement the aim. The analysis results show that a more efficient balancing capacity allocation process should be carried out in a competitive way with closer allocation time to real-time, especially with increased penetration of renewable energy sources. Bid time units, the timing of the market, procurement and remuneration schemes as well pricing mechanisms are the most decisive elements of the market. Their respective advantages and disadvantages are analyzed in the article, as well as their analysis is done against the selected assessment criteria. The results of the analysis show that seeking to improve the operational efficiency of the market, the sequential approach to the market organization should be selected and short-term market time units should be chosen. It is expected that price efficiency could be improved by establishing an organized market where standardized system balancing products should be traded. The balance service providers, who own capital expenditures (CAPEX) sensitive production units, should be remunerated both for the availability of balancing capacities and for their utilization. Uniform pricing rule and cascading procurement principal should be applied to improve the utilization efficiency

Future electricity market structure to ensure large volume of RES

The article define set of rules for future Electricity market structure, taking into account network codes, legislation and directives to ensure RES integration targets and Energy Union Dimensions in term of a fully integrated internal energy market and transition to a long lasting low-carbon society. Presented research studies are based on new way of power system operation development, namely Web-of-cell concept, of FP7 IRP ELECTRA. It’s aiming to ensure conceptual E-market design and future power system 2030+ control solutions

THE BALTIC POWER SYSTEM BETWEEN EAST AND WEST INTERCONNECTIONS

Due to historical and geographical reasons, the Baltic States are strongly connected to the power (electricity) transmission grids of Russia and Belarus. Current energy security and energy independence targets in the EU trigger seeking for alternative power sources for the Baltic. Knowing that, a power system model of the Baltic States has been developed and validated with the purpose of providing comparative options for a reliable and secure development of the Baltic electricity system. The analysis of horizon 2020 and 2030 showed that the dependency of Baltic States on the outside resources is fairly low, provided that the expansion of the electricity system goes as planned.JRC.F.3-Energy Security, Systems and Marke

Flexibility Assessment Through Local Energy Consumer

The paper describes modelling experience in flexibility assessment for local energy consumer. Energy Management System strategies were carried out in order to facilitate pricebased demand response for future implementation as consumer flexibility tool. The case studies were tested with the aim of providing and identifying the load flexibility potential through elaborated scenarios and innovative technology implementation at distribution level. The results of the study were summarized and analysed in the paper

Assessment of flexibility in different ancillary services for the power system

To handle the changing power system and enable the energy transformation, several actions are needed, where the increase of digitalization, automation and more substantial production variability implies a need for flexibility. Solutions providing advances in flexibility are of importance for the future power system. The paper will contribute with knowledge that will support the diversified and efficient use of flexibility, making the electricity system more flexible and delivering the benefits for all system stakeholders. This will both be based on a review of definition and classification of flexibility, flexibility assessment solutions and example of how flexible resources can be utilized in different ancillary services. Different use cases have been developed showing how flexible resources can be utilized in different ancillary services, such as voltage control, management of bottlenecks in the distribution grid and balancing services. The use cases also include a description of the stakeholders involved. Index Terms: Flexibility, Congestion Management, Ancillary services, Voltage ControlacceptedVersio

Flexibility benefits for Power System Resilience

As cheap and affordable variable Renewable Energy Sources (vRES), such as wind farms and photovoltaics, are foreseen to dominate the future energy mix, the abundance of green electricity will allow the replacement of fossil fuels in sectors such as heating, cooling, industrial processes, and transport. The intermittency and/or low controllability of vRES implies the signi..
