Embodiment

[0206] This example applies the power planning method of the power grid at the sending end considering demand response and comprehensive benefits to a region A in my country to realize the power supply expansion demand in this region in 2020, focusing on demand response and comprehensive benefits, and considering the participation of new energy in peak regulation , local load peak-shaving capacity, channel constraints, clean energy curtailment costs, and peak-shaving demands. Hydropower accounts for the majority in this region. In 2017, various types of units were installed as follows: 85.97 million kilowatts of hydropower, 33.61 million kilowatts of thermal power, 2.44 million kilowatts of wind power, 2.26 million kilowatts of solar energy, and 260 million kilowatts of other types of units, totaling 124.54 million kilowatts. In 2020, it is planned to increase the unit capacity as follows: 23.8 million kilowatts of thermal power, 120.25 million kilowatts of hydropower, 48.5 mill...

Abstract

The invention relates to a transmitting end grid power supply planning method in consideration of demand response and comprehensive benefit, comprising the following steps of obtaining system data tobe planned; establishing a power supply planning two-layer model aiming at maximizing comprehensive benefit, wherein the upper layer is an investment decision Layer, and the lower layer is a running simulation layer; solving the power supply planning two-layer model by using an improved hybrid particle swarm optimization algorithm to obtain an optimal power supply planning scheme; obtaining the comprehensive benefit based on random production simulation cost, load shedding cost, demand response cost, and energy abandonment cost and the power generation income in consideration of demand response dynamic power price, wherein the demand response dynamic demand response is obtained by establishing a demand response model with a goal of new energy consumption, and obtaining the dynamic power price under each typical scene according to an elastic power price calculation method. Compared with the prior art, the method has the advantages of high accuracy, strong adaptability and high efficiency.

Description

technical field [0001] The invention relates to the technical field of power system power supply planning, in particular to a power supply planning method for a sending-end power grid considering demand response and comprehensive benefits. Background technique [0002] Demand response means that when the price of the wholesale electricity market rises or the reliability of the system is threatened, the electricity user changes its inherent habitual electricity consumption pattern after receiving the direct compensation notice from the power supply party to reduce the load or the signal of the electricity price rise. , to reduce or shift the power load in a certain period of time to respond to the power supply, thereby ensuring the stability of the power grid and inhibiting the short-term behavior of rising electricity prices. It is one of the solutions for Demand Side Management (DSM). With the development of immediate response devices, demand response will be one of the im...
