An electricity price model with consideration to load and gas price effects.

Some characteristics of the electricity load and prices are studied, and the relationship between electricity prices and gas (fuel) prices is analyzed in this paper. Because electricity prices are strongly dependent on load and gas prices, the authors constructed a model for electricity prices based on the effects of these two factors; and used the Geometric Mean Reversion Brownian Motion (GMRBM) model to describe the electricity load process, and a Geometric Brownian Motion (GBM) model to describe the gas prices; deduced the price stochastic process model based on the above load model and gas price model. This paper also presents methods for parameters estimation, and proposes some methods to solve the model.

New utilization scheme for large-scale wind power farm in North China

During the twelfth Five-Year Program of China, three wind power bases with capacity greater than 10 GW will be established in North China. Rapid development of wind power brings opportunity and challenge to the North China Power Grid. With the analysis of the difficulty in wind power utilization, referring to the Renewable Portfolio Standard (RPS), based on the power retail mode, a novel conception of green power utilization mechanism is proposed. To solve the problem of effectively utilizing the huge wind power, accounting for the status and characteristics of thermal power in North China, two types of bundled outward transmission modes for the Inner Mongolia and Hebei grids are proposed. Under the non-grid-connected wind power mode, large customers can use wind power directly rather than via the Power Grid. Soft- and hardware conditions for developing the wind power utilization are discussed.
