Short-term generation scheduling optimization method considering peak shaving market clearing

Abstract

The invention discloses a short-period generation schedule optimization method considering peak shaving market clearing, which comprises constructing a peak shaving demand analysis model and analyzingsystem peak shaving demand; If there is demand for peak shaving in the system, based on the existing short-term generation scheduling optimization model, a short-term generation scheduling optimization model considering market clearing of peak shaving is constructed. Through the short-term generation scheduling optimization model considering peak shaving market clearing, the unit output planningand thermal power unit deep peak shaving results are obtained. The demand for peak load regulation is analyzed, This paper constructs a short-term generation scheduling optimization model consideringpeak shaving market clearing, realizes the integration of peak shaving market clearing and short-term generation scheduling, promotes fair competition in peak shaving market, encourages thermal powerunits to participate in deep peak shaving, fully tap the system peak shaving potential, and meets the increasingly lean demand of new energy consumption and safe operation of large power grids.

Description

technical field [0001] The invention relates to a method for optimizing a short-period power generation plan considering the clearing of a peak-shaving market, and belongs to the technical field of power system scheduling automation. Background technique [0002] With the vigorous advancement of the country's new energy construction, a large number of new energy sources in Ningxia Power Grid have been put into operation. Up to now, the installed capacity has reached 15.96 million kilowatts, including 9.76 million kilowatts of wind power and 6.2 million kilowatts of photovoltaic power, accounting for 40% of the total installed capacity. At the same time, the proportion of installed heat generators continues to increase, accounting for about 40% of the installed capacity of thermal power under unified control. The start-up method of thermal power is more restricted, especially during the heating period. The power grid is under great pressure for peak regulation. [0003] In Ma...
