Generation Expansion Planning (GEP) is one of major modules of power system planning studies, normally performed for the nex 10-30 years horizon. The current industrial practices are to find the generation requirements based on a&#10&#10nodal analysis. In this way, the allocations are not determined and subequent studies are required to find the exact locations &#10 which as decomposed from the...

This paper presents a method in expansion planning of transmission systems using the AC optimal power flow (AC-OPF). The AC-OPF provides a more accurate picture of power flow in the network compared to the DC optimal power flow (DC-OPF) that is usually considered in the literature for transmission expansion planning (TEP). While the AC-OPF-based TEP is a mixed-integer nonlinear programming prob...

This paper discusses probabilistic methodology for Transmission System Planning. Recent NESCOE memo suggested that current transmission planning procedure at ISO-NE might create inconsistency within the region and between the development plans of various transmission owners. The proposed methodology establishes base cases and contingency testing as means for consistent probabilistic assessment ...

In deregulated power systems, the transmission loss allocation plays a key role in planning and designing of the power system. In practice, these losses should be allocated to both generators and loads depending on the amount of contribution in the total power system losses. In this paper, a new methodology to optimally allocate the transmission losses to either generators or loads based on the...

The study of a decentralized coalition formation scheme in an speci c Power Systems transmission expansion scenario is the purpose of this paper. We dene rst who are the players in the expansion game, and provide a decentralized coalition scheme based on Bilateral Shapley Values. We study the stability properties of our approach to allocate expansion costs to all coalition members. Finally, the...

As environmental criteria become more and more important for the energy systems operation and planning, this paper proposes a method that can support the decision makers in future electricity systems planning. The evaluation of future electric power transmission investment plans is based on a social welfare analysis when the external costs of production are internalized. The social benefit can ...

GSA; Real power loss; Reactive power planning; FACTS; Optimization Abstract In this paper, Gravitational Search Algorithm (GSA) is used as optimization method in reactive power planning using FACTS (Flexible AC transmission system) devices. The planning problem is formulated as a single objective optimization problem where the real power loss and bus voltage deviations are minimized under diffe...

using new approaches to optimize the process of power transmission line routing can solve many complex problems which power transmission line routing decision-makers are faced. due to the expansion of involved parameters we can consider multi-objective evolutionary algorithms as appropriate method in this area. in this thesis with using multi-objective evolutionary algorithms nsga-ii and offere...

Deregulation and restructuring have become unavoidable trends to the power industry recently in order to increase its efficiency, to reduce operation costs, or to provide customers better services. The once centralized system planning and management must be remodeled to reflect the changes in the market environment. We have proposed and developed a multi-agent based system to assist players, su...

The ubiquity of synchronous generation should not be assumed in highly renewable power systems. Various problems may consequently arise: not least, the difficulties entailed in maintaining regional reactive power balance. Offering a potential solution to such problems, modern renewable generator technologies offer controllable reactive power resources. As many of these generators will be embedd...
