Virtual power plant peak regulation method based on incentive electricity price

Abstract

The invention discloses a virtual power plant peak regulation method based on incentive electricity price, and belongs to the technical field of economic operation and optimal dispatching of a power system. The method comprises the following steps: step 1, carrying out load prediction on a power grid dispatching control center before an operation day, and issuing load characteristics, peak regulation demands and weather prediction data of the next day; 2, enabling the virtual power plant control center to formulate excitation electricity prices in all time periods by using the data obtained in the step 1, and determining a scheduling plan; 3, determining the response capability of the load in each time period, and forming a day-ahead peak regulation plan by the virtual power plant; according to the output of the virtual power plant and the conventional unit, enabling the power grid dispatching control center to formulate a day-ahead peak regulation plan of the virtual power plant and the conventional unit; and 4, correcting the day-ahead peak regulation plan on the operation day to form an intra-day peak regulation plan. The maneuverability and flexibility of the demand side distributed resources participating in the power grid are fully improved, and the invention has good application value.

Description

technical field [0001] The invention relates to the technical field of economical operation and optimal dispatching of power systems, in particular to a peak regulation method for a virtual power plant based on an incentive electricity price. Background technique [0002] In recent years, renewable energy power generation technology has achieved rapid development due to its cleanliness and environmental friendliness, and has also promoted the rapid increase of distributed photovoltaic installed capacity. The significant increase in the proportion of renewable energy has brought more uncertainty to the operation of the power system. The output of photovoltaic power generation will fluctuate greatly with meteorological changes, which undoubtedly increases the difficulty of peak regulation of the system. On the other hand, to construct a clean, low-carbon, safe and efficient new-generation power system, it is necessary to further improve the vitality of demand-side distributed ...
