Case studies validate the effectiveness and high performance of the proposed distributed expansion method and the solution procedure.Prefabricated substations, also known as European type substations. The iteration solution algorithm is used to transform the robust min–max-min problem for transmission expansion into a two-stage mixed-integer linear programming problem, and coordinate transmission and distribution expansion problems in a parallel manner.
To guarantee the consistency of transmission-distribution interaction, the deviation penalties of the interactive power are introduced into the objective function of each level. Uncertainty sets are deployed to model the uncertainties in TN while the scenario-based technique is implemented to tackle the uncertainties in DNs. This paper proposes a distributed decision-making framework to determine the robust TN expansion solution and stochastic DN expansion solutions. Coordinated expansion of transmission and distribution networks is the key to the economic and reliable operation of the integrated system in the future uncertain environment. The plurality of active distribution networks (DNs) has made it ready to connect the transmission network (TN) for the dynamic power interaction. The results also show that congestion in transmission lines can considerably affect the strategic decisions of DISCOs on DG investment. The results show that ignoring the action of other DISCOs may lead to the over‐ or under‐investment in DG sector which consequently decreases the DISCOs’ profit. The methodology proposed is applied to the IEEE 24‐bus RTS with several 24‐bus DNs. The generalised Nash equilibrium problem is further formulated as a mixed‐integer linear program using Karush–Kuhn–Tucker conditions.
Primal–dual formulation is used to convert the bilevel problem into a single level one resulting in a discretely‐constrained generalised Nash equilibrium problem. In doing so, a novel bilevel game‐based framework is presented to coordinate the decisions of DISCOs for distribution expansion planning problem. Accordingly, the main motivation of this study is to propose a coordinated expansion scheme among distribution companies (DISCOs). Hence, an uncoordinated expansion planning may lead to redundant investment cost and suboptimal solutions. However, DNs are being converted from passive to active mode by extensively integrating distributed generations (DGs) into them. The expansion planning of a distribution network (DN) is studied separately and independently from the behaviour of the transmission network (TN) as well as other DNs.
