Study On Timed Price Model Of Power Corporation With Independent Power Source

A timed pricing model for power corporation with independent power source such as independent power plant and pumped storage is proposed as the result of study on electricity price,which is based on timed pricing form and marginal cost. Electricity energy is considered as the commodity,the power corporation as modern enterprise. Specialty of price and arithmetic of model based on market economy rule are designed. Electricity market user demand forecasting,power corporation costs calculating,mathematic modeling of timed price and the model programming are the main parts of the paper.Operations of the power corporation include power energy sending,purchasing,selling,pumped storing and timed balancing. In the model trading price and trading quantities of all operations are considered as model parameters,as well as operating profit as model objects. At the same time the response of user rose by price quivering,generation cost curve and unit parameters of independent power plant and pumped storage are considered as restriction. It is a linear programming model of trading price and quantities and which can be solved using simple shape arithmetic,and is proved reasonable and validity by the simulated result.
