ISOs and RTOs of North America as of 2024. The California Independent System Operator (CAISO) is a non-profit Independent System Operator (ISO) serving California. [1] It oversees the operation of California's bulk electric power system, transmission lines, and electricity market generated and transmitted by its member utilities.
The grid operators forecast load and schedule generation to assure that sufficient generation and back-up power is available in case demand rises or a power plant or power line is lost. They also operate wholesale electricity markets that enable participants to buy and sell electricity on a day-ahead or a real-time spot market basis. These ...
Virtual bidding is a strategy implemented in various Independent System Operator electricity markets of trading Day-Ahead prices against Real-Time (or Hour-Ahead) prices. The term "bid" can be used loosely in electricity markets to refer to an offer to buy or to sell.
Short-term forecasting [18] generally involves horizons from a few minutes up to a few days ahead, and is of prime importance in day-to-day market operations. In load forecasting, very short-term forecasting with lead times measured in minutes is often considered as a separate class of forecasts. [19] Medium-term forecasting, from a few days to ...
Medium-term forecasting, from a few days to a few months ahead, is generally preferred for balance sheet calculations, risk management and derivatives pricing. In many cases, especially in electricity price forecasting, evaluation is based not on the actual point forecasts, but on the distributions of prices over certain future time periods.
Applications of power system simulation include: long-term generation and transmission expansion planning, short-term operational simulations, and market analysis (e.g. price forecasting). These programs typically make use of mathematical optimization techniques such linear programming , quadratic programming , and mixed integer programming .
Graphs by hour of California's total electric load, the total load less solar and wind power (known as the duck curve) and solar power output. Data is for October 22, 2016, a day when the wind power output was low and steady throughout the day. In electrical engineering, a load profile is a graph of the variation in the electrical load versus ...
Information used for the solar power forecast usually includes the Sun´s path, the atmospheric conditions, the scattering of light and the characteristics of the solar energy plant. Generally, the solar forecasting techniques depend on the forecasting horizon Nowcasting (forecasting 3–4 hours ahead), Short-term forecasting (up to seven days ...
