    Distributed transactive framework for congestion management of multiple-microgrid distribution systems

    , Article IEEE Transactions on Smart Grid ; Volume 13, Issue 2 , 2022 , Pages 1335-1346 ; 19493053 (ISSN) Fattaheian Dehkordi, S ; Rajaei, A ; Abbaspour, A ; Fotuhi Firuzabad, M ; Lehtonen, M ; Sharif University of Technology

    Abstract
    The privatization of distribution systems has resulted in the development of multiple-microgrid (multiple-MG) systems where each microgrid independently operates its local resources. Moreover, the high integration of independent distributed energy sources could lead to operational issues such as grid congestion in future distribution systems. Therefore, this paper provides a transactive-based energy management framework to operate multiple-MG distribution systems; while, alleviating grid congestion in a decentralized manner. In this respect, alternating direction method of multipliers (ADMM) is considered to develop an operational framework that copes with distributed nature of multiple-MG...

    Developing a distributed robust energy management framework for active distribution systems

    Abstract
    Restructuring and privatization in power systems have resulted in a fundamental transition of conventional distribution systems into modern multi-agent systems. In these structures, each agent of the distribution system would independently operate its local resources. In this regard, uncertainties associated with load demands and renewable energy sources could challenge the operational scheduling conducted by each agent. Therefore, this paper aims to develop a distributed operational management for multi-agent distribution systems taking into account the uncertainties of each agent. The developed framework relies on alternating direction method of multipliers (ADMM) to coordinate the...

    Abstract
    The introduction of microgrids (MGs) and renewable energy sources (RESs) has caused significant shifts in the operation of power systems. Despite many benefits, integration of RESs has emerged new issues in the power systems operation. One of the issues recently raised by some utilities, is the severe ramps which are seen in systems with high penetration of RES. On the other hand, the traditional flexible power plants could not provide the ramp required in these systems. As a result, flexible local resources in independent entities like MGs should be employed to tackle this issue in these systems. In this paper, a novel model is developed to investigate the effects of MGs and gas grid...
