Regional comprehensive energy device and network dual-layer optimization configuration method

Abstract

The present invention discloses a regional comprehensive energy device and a network dual-layer optimization configuration method, belonging to the field of regional comprehensive energy planning. Themethod comprises the following steps that: comprehensive energy is divided into electrical / gas / thermal / cool energy systems according to load demands, coupling relations among different energy systemsare considered to establish a regional comprehensive energy device and a network planning model consisting of an upper layer planning model and a lower layer planning model, the lower layer planningis employed to perform decoupling solution of the electrical / gas / thermal / cool energy systems, maximum power of the device and the line is output, and feedback is performed to the upper layer; and theupper layer planning considers the device and network installation capacity constraint and performs solution, device capacity and line layout variables are output to regulate the lower layer, iteration solution is performed until convergence, and the device and network planning is achieve according to the obtained device capacity and a line layout result. The regional comprehensive energy device and the network dual-layer optimization configuration method have advantages of coupling planning of the electrical / gas / thermal / cool energy systems, reduction of establishing investment of the comprehensive energy area and reduction of system operation loss.

Description

technical field [0001] The invention relates to the field of regional comprehensive energy planning, in particular to a method for regional comprehensive energy equipment and network double-layer optimal configuration. Background technique [0002] Energy and environmental issues have become the focus of attention of all countries in the world. Seeking new energy, improving energy efficiency, and large-scale development and utilization of renewable energy are inevitable choices for achieving sustainable energy development. In addition, user terminal energy demand forms are diversified, including electricity, gas, heat / cold and other forms, such as ordinary electricity load, heating load, hot water load, gas load, etc. In this context, the existing energy industries such as cooling, heating, electricity, and gas are relatively closed, and the traditional model of separate planning and independent operation restricts the improvement of comprehensive energy efficiency, which is...

Problems solved by technology

However, this invention only established a heating network model to solve the problems of configuration waste and low equipment utilization in separate planning, without considering the production, conversion, transmission, and consumption of different forms of energy such as electricity, gas, cooling, and heat. Due to the existing coupling relationship, the optimal planning scheme cannot be determined, and the equipment and network planning of the comprehensive energy area cannot be realized according to the obtained equipment capacity and line layout results
