California's enactment of a 20% Renewables Portfolio Standard (RPS) by 2010 and an announced policy preference for an increase to 33% by 2020 poses operational and electricity market challenges associated with integrating such high levels of renewable resources into the state's existing transmission system. The output of wind, solar, and ocean generation resources vary according to the availability...
Summary form only given. The profitable operation of a wind project depends on two critical indices: wind energy deliverability and locational marginal prices (LMP). The traditional optimal power flow (OPF) study has been widely used to obtain those indices. However, the traditional OPF study generally provides only the peak load hour results, which ignore temporal constraints of power system components...
This paper proposes a practical and effective model for the generation forecasting of a wind farm with an emphasis on its scheduling and trading in a wholesale electricity market. A novel forecasting model is developed based on indepth investigations of meteorological information. This model adopts a two-stage hybrid network with Bayesian clustering by dynamics and support vector regression. The proposed...
Wind plants that act as merchants in electricity markets are subject to adverse market conditions that result from the stochastic nature of the power they generate. The inability of these merchant wind plants to follow a deterministic power generation schedule exposes them to the volatility of real-time energy prices and, in some markets, to charges based upon their deviations from a predetermined...
The results of investigations to identify and quantify the effects of large scale wind generation on the operation of the New Zealand power system and electricity market are presented. The effects of variability of wind generation output and technological capability of wind generation turbines are considered. The variability of wind generation output, wind generation forecasts and management of large...
Uncertainty and variability in the wind resource create obstacles for the participation of wind power in forward markets, such as regional day ahead electricity markets. Studies performed in various states have developed methods to improve wind forecasting and so reduce the inherent uncertainty in a day ahead schedule for wind power generation. This paper addresses the issue of the variability in...
The purpose of this paper is to discuss some of the operational concerns as the amount of wind generation in our area increases over the next 5 years. The addition of 4500 more megawatts of wind generation in California will have an impact on both the transmission system and real-time operation of the California power grid. This paper focuses on the operational issues due to the intermittent nature...
