Photovoltaic power station bidding optimization method based on consideration of energy storage demand response effect

Abstract

The invention discloses a photovoltaic power station bidding optimization method based on consideration of an energy storage demand response effect. The method comprises the steps of obtaining a comprehensive price incentive value of a system operator for a photovoltaic output curve based on preset evaluation index data; calculating the expected electricity selling income of the photovoltaic powerstation based on the photovoltaic output basic rate, the comprehensive price excitation value, the bidding curve and other data, and calculating the cost of purchasing the energy storage resources with the demand response effect; and establishing a photovoltaic power station expected revenue maximization objective function, iteratively searching an expected revenue maximum value through an intelligent optimization algorithm, and obtaining a bidding curve and an energy storage effect demand response resource purchase strategy when the expected revenue maximum value is obtained. The incentive price mechanism is added into the expected revenue maximization objective function of the photovoltaic power station, so that the photovoltaic power station can be forced to purchase the energy storageresource with the demand response effect, the energy storage resource with the demand response effect is reasonably utilized and purchased, and power generation of the photovoltaic power station is more economical.

Description

technical field [0001] The invention relates to the technical field of electric power market, in particular to a bidding optimization method for photovoltaic power plants based on consideration of energy storage demand response. Background technique [0002] Under the environment where primary energy sources such as oil and natural gas have caused excessive pressure on the ecological environment, people are gradually focusing on cleaner renewable energy sources, and the efficient use of photovoltaics is one of them. With the continuous increase of photovoltaic installed capacity in my country, the randomness, volatility and instability of photovoltaic output itself lead to the insufficient consumption of centralized photovoltaic by the power grid, which affects the safe and stable operation of the power system, and needs to be formulated in a targeted manner. Consumption mechanism. Under the existing consumption mechanism, photovoltaic power plants can only passively bear the...

With the continuous increase of photovoltaic installed capacity in my country, the randomness, volatility and instability of photovoltaic output itself lead to the insufficient consumption of centralized photovoltaic by the power grid, which affects the safe and stable operation of the power system, and needs to be formulated in a targeted manner. Consumption mechanism. Under the existing consumption mechanism, photovoltaic power stations can only passively bear the ancillary service fees generated after entering the grid.
