Electricity generating schedule optimizing method considering pump storage unit

Abstract

The invention belongs to the technical field of dispatching automation of electric power systems and relates to an electricity generating schedule optimizing method considering a pump storage unit. Minimization of the electricity generating cost of the systems is taken as the target, coordinated dispatching of the pump storage unit and a conventional thermal electricity generating unit is comprehensively considered, various constraint conditions are considered for optimizing and calculating electricity generating schedules of the units, and the intelligence level and the decision-making ability of electricity generating dispatching after pumped storage is connected are improved helpfully. Meanwhile, the method has the advantages of being low in calculated strength and high in adaptability, and can be more suitable for being applied to and popularized in dispatching mechanisms, large in installed capacity, of the pump storage unit in our country.

Description

technical field [0001] The invention belongs to the technical field of power system scheduling automation, and relates to a power generation plan optimization method considering a pumped storage unit. Background technique [0002] At present, energy saving, emission reduction and curbing climate warming have become a common challenge and an important issue facing the whole world. The Chinese government attaches great importance to the work of energy conservation and emission reduction in the power industry, and proposes to implement energy-saving power generation dispatching in the power field, improve the efficiency of energy use in the power industry, reduce environmental pollution, and promote the adjustment of energy and power structures. This is a major measure for the electric power industry to implement the scientific outlook on development and build a harmonious socialist society, and it is an inevitable choice for building a resource-saving and environment-friendly ...

Problems solved by technology

However, in the actual application process, the operating state of the pumped storage unit is complex, and only the output of the pumped storage unit is used as a constraint condition, without considering the constraints of other factors of the pumped storage unit. Repeated adjustments to the unit combination plan in the center have brought a huge workload to the operating personnel

The patent CN103699938A is based on the particle swarm algorithm, which obtains the output of the locally optimal pumped storage unit and conventional thermal power unit. In actual use, continuous adjustment is required to obtain the globally optimal pumped storage unit and conventional thermal power unit. The effort has brought a huge workload to the operators
