  This paper introduces a demand-side distributed and secured energy commitment
framework and operations for a Power Producer and Supplier (PPS) in deregulated
environment. Due to the diversity of geographical location as well as
customers' energy profile coupled with high number of customers, managing
energy transactions and resulting energy exchanges are challenging for a PPS.
The envisioned PPS maintains several aggregators (e.g. Microgrids), named as
Sub Service Provider (SSP) that manage customers/subscribers under their
domains. The SSPs act as agents that perform local energy matching (inside
their domains) and distributed energy matching within SSPs to determine the
energy commitment. The goal of the distributed energy matching is to reduce the
involvement of External Energy Supplier (e.g. Utility) while providing a
platform to demand side players to be a part of energy transaction. A
distributed assignment problem is designed that requires minimum and aggregated
information exchange (hence, secured) and solved by Linear Programming (LP)
that provides the distributed matching decision. The communicative burden among
SSPs due to the exchange of energy information is reduced by applying an
adaptive coalition formation method. The simulations are conducted by
implementing a synchronous distributed matching algorithm while showing the
effectiveness of the proposed framework.
