The electric industry is developing towards a more efficient, reliable, and resilient electric power network. In this way, utilizing distributed energy resources (DERs), especially renewable DERs (RDERs) are a paradigm change. DERs offer many advantages in power systems, including transmission loss reduction, environmental benefits of RDERs, and enhancement of security, reliability, and resiliency of the network. However, high penetration of DERs increases uncertainty and challenges the efficient and reliable operation of the power system. This paper provides a thorough review of the transactive distribution platform which is essential to address the aforementioned challenges. This distribution platform includes a transactive distribution system operator providing a seamless and coordinated control to dynamically balance supply and demand and follow uncertain generations of RDERs. Indeed, this review paper highlights the capability of transactive energy (TE) by considering its key aspect in providing energy sharing opportunities for the integration of DERs into smart grids (SGs). TE is acombination of economic and control methods that enable optimum, reliable, sustainable, and efficient operation of SGs. Furthermore, a fully transactive framework offers more choices for DERs to control and manage the energy transactions in the retail market, as well as improves the inter operability among various market players. 

Transactive energy revolution: Innovative leverage for reliable operation of modern energy networks—A critical review

Decision-making model with reduced risk of penalties in transactive energy markets

The increasing integration of renewable energy resources (RERs) and the expansion of multi-microgrid systems have transformed the operational condition of power systems. Respectively, the high-amount installation of RERs could result in the volatile changes exchanged-power of local systems, when their power generation drops suddenly. Nevertheless, the available ramp-up power for compensating the supply-demand gap in the power system could be limited due to the operational constraints of power networks and generation units. As a result, in this article, a transactive flexible-ramp-up-management-mechanism is offered in order to enable system operators to exploit the scheduling of microgrid systems with the aim of ensuring power requirements of the multi-microgrid system meet the flexible-ramp-up constraints. Therefore, the mechanism would result in the efficient rescheduling of local flexible resources in a multi-microgrid distribution system in order to address the ramp-up constraints in the system. The offered mechanism limits the information exchange between microgrids and the system operator to transactive control signals and accumulated power exchanges to impede privacy concerns of independently operated entities. Lastly, the recommended mechanism is implemented on the IEEE-37-bus test system, where, its effectiveness in addressing the overall system flexible-ramp-up limitations is investigated.
