Micro-energy network system and collaborative optimization operation control method thereof

Abstract

The invention relates to a micro-energy network system and a collaborative optimization operation control method thereof. Specific equipment contained in an energy supply side and an energy conversiondevice is reasonably configured; the formed micro-energy network system has the advantages that the new energy access proportion is higher; configuration can be optimized through the energy storage device; the power grid, the heat supply network and the air network meet the energy requirements of users; basic balance between local energy production and user energy consumption load is achieved; the collaborative optimization operation control method is used for carrying out rolling optimization on the micro-energy network system, the power output value of controllable energy supply equipment in the micro-energy network system is continuously adjusted, the micro-energy network system is made to operate economically on the premise that the real-time balance of supply and demand is met, and therefore the purpose of saving energy is achieved. Energy consumption, energy supply and energy storage are uniformly and cooperatively dispatched, multi-energy supply complementation in a micro-energy network system is achieved, the comprehensive utilization efficiency and stepped utilization of multi-energy supply in a micro-energy network are improved, emission is reduced, and local consumptionof energy is achieved.

Description

technical field [0001] The invention relates to the field of comprehensive energy utilization, in particular to a micro-energy network system and a cooperative optimization operation control method thereof. Background technique [0002] Energy is an important guarantee for human survival and the lifeblood of economic and social development. With the development of society and the improvement of people's living standards, human demand for energy is increasing year by year, resulting in the depletion of primary fossil energy and increasingly severe environmental problems. The disadvantages of traditional energy development and utilization are becoming more and more obvious, and energy transformation is imperative. To improve energy efficiency and reduce CO 2 To realize the sustainable development of society, people pay more and more attention to the way of combining the traditional energy system with renewable energy such as solar energy and wind energy. And born. However, ...

Problems solved by technology

[0003] At present, the operation of the micro-energy grid is mainly based on the Combined Cooling Heating and Power (CCHP) system, which assists wind, light and other renewable energy power generation, and in terms of load, it is only divided into cooling load, heating load and The electric load does not refine the energy demand of users, and at the same time, it does not consider the step-by-step utilization of energy and the comprehensive utilization of renewable energy on the energy supply side and energy consumption side, resulting in insufficient comprehensive energy utilization efficiency and restricting renewable energy.
