“…This means that the problem solved in this paper does not include Kirchhoff's constraints among the power flows through the transmission lines. In addition the transmission capacities can vary depending on the flow's direction [24]. This transportation approach is commonly used in the representation of major inter-regional transmission constraints.…”

“…This transportation approach is commonly used in the representation of major inter-regional transmission constraints. Simplifying Kirchhoff's laws into a transportation model [24] and considering perfectly inelastic demand, 4 [19] becomes (1) 2 Two nodes and belong to the same area , neglecting network losses, when their nodal prices are equal and when they are interconnected by a path of nodes with same price. 3 Existence and uniqueness cannot be guaranteed when including technical constraints such as generation maximum capacities.…”

“…From January 2002 until December 1, 2010 ERCOT operated with a zonal market structure, in which power flows between zones were regulated with commercially significant constraints (CSCs), which were calculated every year [23]. CSCs consider the thermal and capacity limits of the simplified lines as well as the possible contingences [24] to limit power flows over lines, but might not consider the existence of local transmission constraints that affect the companies' strategies. ERCOT has been extensively treated in market power studies [1], [5], and [13].…”

Previous studies of market power within a regional system have considered multiple competing generation operators and the role of transmission constraints. However, these studies typically assume simplified structures in which each operator is restricted to a unique node in a transmission constrained network. Real systems typically have operators making decisions for units in several zones at once. Past studies also implicitly treated market power as a static concept for a given set of market rules and network configuration. We demonstrate that market power is dynamic, and can vary significantly with fuel prices and even with large-scale weather patterns. We also demonstrate the impact on region-wide market power of operators that manage units in multiple zones. We use the Electric Reliability Council of Texas (ERCOT) as an illustrative case study, and apply a conjectured supply function equilibrium (CSFE) approach that accounts for transmission constraints. We show that the companies with greater influence on the market price will depend on the relative prices of coal and natural gas. We also show that a weather event, such as a period without any wind, can have a substantial impact on market power.

This paper proposes a transmission planning framework in a market environment in which only the generation sector is deregulated. The proposed framework is based on modeling generation companies' (GenCos') strategic behavior and anticipating their expansion patterns from the viewpoint of a transmission system planner. The transmission expansion planning problem in this paper is modeled as a four-level optimization problem. A solution method based on agent-based systems and search-based optimization techniques is proposed to determine the optimal transmission expansion plan.
