2020 FEB 12 (NewsRx) -- By a News Reporter-Staff News Editor at Energy Daily News -- A new study on Energy - Smart Grids is now available. According to news reporting from Pullman, Washington, by NewsRx journalists, research stated, “Increasing penetration of proactive agents, including distributed energy resources (DERs) and responsive loads (RLs), in distribution systems motivates methods to incentivize market participation from demand-side resources. The complexity resulting from large-scale integration of proactive agents has challenged the viability of centrally managing grid resources in a distribution system environment and motivated decentralized frameworks to coordinate the transactions.”

Financial support for this research came from U.S. Department of Energy (DOE).

The news correspondents obtained a quote from the research from Washington State University, “Existing decentralized frameworks are primarily focused on designing transaction mechanisms. They neither include a formal market construct nor a computationally feasible approach for market settlement for a large volume of transactions while ensuring the security of grid operation. This paper presents a distributed computational approach for a distribution system market where the coordination framework is based on agreement on bilateral energy transactions reached by market participants. Using the proposed distributed computational method, participants play a role in determining the set of bilateral transactions that maximizes the social welfare. The distribution system operator (DSO) ensures a secure operating condition of the distribution grid by validating each transaction that is agreed upon. Under a potential violation of security constraints by a proposed bilateral transaction, the DSO runs an optimal power flow (OPF) and recommends a new set of transactions (closest to those previously proposed) while maintaining power system security. The proposed framework is validated using IEEE 123-node test system.”

According to the news reporters, the research concluded: “The results confirm the feasibility of the proposed approach for distribution systems.”
