Improved Transmission Representations in Oligopolistic Market Models: Quadratic Losses, Phase Shifters, and DC Lines Practical models of competition among power generators who possess market power have generally had to use simplified models of transmission costs and constraints in order to be tractable. In particular, the linearized dc load flow model has been popular in complementarity and other types of oligopoly models. In this paper, we show how such models can be generalized to include quadratic losses, controllable DC lines, and phase shifting transformers.

Recognition of Extended Dispatch Horizons in California’s Energy Markets Effective in 2009, the California ISO launched a new market structure that combines advanced unit commitment and dispatch processes with recognition of physical characteristics of the transmission system and generation resources. California’s upcoming implementation of aggressive targets for renewable energy will result in new, profound changes in markets and system operations. The CAISO is responding by making additional improvements in its unit commitment processes.

Management of Available Transfer Capability with Growth in Renewable Resources The California ISO’s functions include energy and related markets that provide non-discriminatory access to transmission facilities that have been placed under the CAISO’s operational control. The calculations of available transfer capability (ATC), and management of market schedules to remain within ATC, are critical parts of the CAISO’s functions. This paper describes these functions. An emerging challenge in management of California’s transmission grid is an increasing reliance on renewable generation, to achieve aggressive targets to reduce the current heavy reliance on natural gas as a fuel for electric generation and to reduce emissions of carbon dioxide, which will result in profound changes in markets and system operations.

Transmission Expansion Planning in the Western Interconnection This paper describes the evolving transmission expansion planning process and the role OPF1 modelling plays in aiding decision-making and consensus building. It identifies some opportunities for improvement in modelling, highlights two state-of-the-art models with capabilities that go beyond those of other models currently used for long-term transmission planning and makes a case for why we need to invest in better modelling and databases.

CAISO Study Using PLEXOS: Integration of Renewable Resources, Operational Requirements and Generation Fleet Capability at 20% RPS This study identifies the maximum values of simulated operating requirements, such as load following and regulation, by operating hour and by season. In addition, to clarify how more typical daily operations may change, distribution statistics are provided for most of the simulated requirements and capabilities to facilitate both operational and market preparedness.

Modelling CO2 Emissions Impacts on Croatian Power System Analysis presented in this paper was done by two different models: mathematical model, based on short run marginal costs (SRMC, relevant for fuel switch in existing power plant and merit order change) and long run marginal costs (LRMC, relevant for new investment decisions); and electricity market simulation model PLEXOS, which was used for modelling Croatian power system during development of the Croatian Energy Strategy in 2008.

Energy Forecasts to Ireland 2020 – Section 8 This report extends beyond the headline forecast and presents some detail on new areas of modelling being explored by SEAI. Construction of a bottom-up energy demand model for Ireland is detailed (LEAP Ireland), together with early results of an expanded electricity modelling capability (PLEXOS Ireland), to investigate the potential of such measures as electrification of residential heat. Details of the bio energy analysis model (BEAM) are provided, along with selected results from the analysis that formed part of the Bio Energy Roadmap.
