Environmental economic dispatching method considering polluted gas emission risk

Abstract

The invention discloses an environmental economic dispatching method considering polluted gas emission risk. The method comprises the steps of defining polluted gas emission risk evaluation indexes in environmental economic dispatching after considering the randomness of wind power output; building the polluted gas emission risk evaluation indexes according to the concept of semi-absolute deviation risk; building a multi-target random dynamic environmental economic dispatching model considering the polluted gas emission risk in daily dispatching cycle according to the multi-scene modeling theory. According to the method, the wind power output scene simulation and the scene reduction technology are combined; the built model is solved by the genetic algorithm that the embedded target is relatively dominant; therefore, the risk information of polluted gas emission in the environmental economic dispatching can be effectively evaluated, and the polluted gas emission risk can be effectively managed.

Description

technical field [0001] The invention relates to the field of risk assessment of wind power output to discharge polluted gas, in particular to an environmental economic scheduling method that takes into account the risk of polluted gas discharge. Background technique [0002] In today's increasingly severe energy shortage and environmental pollution, it is of great practical significance to evaluate and manage the pollution gas emissions of the power system, which accounts for a large proportion of the pollution gas emissions of the whole society. In this context, wind power has developed rapidly in countries all over the world due to its advantages of no consumption of primary energy and no emission of polluting gases. Environmental economic dispatch is an important means to control the emission of polluting gas in the power system. How to consider the randomness of wind power output to realize the evaluation and management of polluting gas emission is a major issue to be so...

Problems solved by technology

The principle of this idea is relatively simple, but if it is applied to the risk assessment of pollutant gas emissions, it will lead to three problems: 1) The determination of PPF for different power structures and load demands in different regions must be different, and the assessment results are not horizontally comparable; 2 ) Due to the artificial introduction of PPF, the assessment results cannot truly reflect the risk of pollutant gas emissions; 3) The assessment results are inconsistent with the current assessment indicators of pollutant gas emissions in various countries and regions
