Abstract: |
From the perspective of transactive energy, the
energy trading among interconnected microgrids (MGs) is
promising to improve the economy and reliability of system
operations. In this paper, a distributed energy management
method for interconnected operations of
combined heat and power (CHP)-based MGs with demand
response (DR) is proposed. First, the system model of
operational cost including CHP, DR, renewable distributed
sources, and diesel generation is introduced, where the DR
is modeled as a virtual generation unit. Second, the optimal
scheduling model is decentralized as several distributed
scheduling models in accordance with the number of
associated MGs. Moreover, a distributed iterative algorithm
based on subgradient with dynamic search direction
is proposed. During the iterative process, the information
exchange between neighboring MGs is limited to Lagrange
multipliers and expected purchasing energy. Finally,
numerical results are given for an interconnected MGs
system consisting of three MGs, and the effectiveness of
the proposed method is verified. |
