Problems solved by technology

[0003] However, in existing studies, when measuring the level of energy utilization, only the change in energy quantity is considered, and the difference in energy quality is not considered; the consideration of energy conversion is not comprehensive enough, especially for the conversion from thermal energy to electrical energy. There are studies; at the same time, the optimization goal usually only considers the economy and environmental protection, while ignoring the efficiency goal

Embodiment Construction

[0118] a consideration The efficient multi-objective optimal scheduling method of the integrated energy system of the park with ORC, the Organic Rankine Cycle (ORC) waste heat power generation can make full use of the waste heat of equipment power generation, so that the unidirectional flow of energy between the traditional thermal network and the power network It is transformed into bidirectional flow, and its combination with the heat storage system provides a new idea for the consumption of wind power and photovoltaics. The present invention proposes a consideration from three perspectives of economy, energy utilization and environment. Efficient dispatching model for multi-objective low-carbon economy of the integrated energy system (IES) of the park with ORC. First, build a park IES including CCHP equipment, hydrogen fuel cells, ORC waste heat power generation and other equipment. Secondly, with the lowest economic cost, The maximum efficiency and minimum carbon emi...

Abstract

The invention discloses an efficiency-considered multi-objective optimization scheduling method for an ORC-containing park integrated energy system. The method comprises the following steps: step 1, constructing the park integrated energy system; step 2, constructing a multi-objective optimization scheduling model; and step 3, aiming at the multi-objective optimization scheduling model in the step 2, solving by adopting an NSGA-II algorithm. According to the dispatching method, bidirectional coupling between the power grid and the heat supply network is achieved, the economic cost and carbon emission of the system are reduced, and the wind power and photovoltaic absorption capacity is effectively improved.

Description

technical field [0001] The invention relates to the technical field of optimal scheduling of comprehensive energy systems in parks, and in particular to a consideration Efficient multi-objective optimal scheduling method for park integrated energy system with ORC. Background technique [0002] The overuse of fossil energy has caused a global energy and environmental crisis, and it has become a global consensus to accelerate green, efficient and sustainable energy development. Renewable energy represented by wind power and photovoltaic can effectively reduce environmental pollution, but the problem of abandoning wind and light is serious. A comprehensive energy system that integrates multiple energy sources and loads has emerged. Through multi-energy complementation and energy cascade utilization, it is one of the effective ways to solve environmental problems and improve energy utilization. However, for the measurement of energy utilization, most researches use the energy...
