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. Full local consumption of energy

Abstract

The invention relates to a micro-energy network system and its collaborative optimization operation control method. By rationally configuring the energy supply side and the specific equipment contained in the energy conversion device, the micro-energy network system formed not only has a higher proportion of new energy access , through the optimized configuration of the energy storage device, the user's energy demand can be met through the power grid, heating network and gas network, and the basic balance between local energy production and user energy load can be achieved. Rolling optimization continuously adjusts the power output value of the controllable energy supply equipment in the micro-energy grid system, and makes the micro-energy grid system operate economically under the premise of meeting the real-time balance of supply and demand, so as to achieve the purpose of energy saving. Unified and coordinated scheduling of energy consumption, energy supply and energy storage, realize the complementarity of multiple energy supplies in the micro-energy network system, improve the comprehensive utilization efficiency and step utilization of multiple energy supplies in the micro-energy network, reduce emissions, and realize energy consumption on the spot.

Description

technical field [0001] The invention relates to the field of comprehensive energy utilization, in particular to a micro-energy grid system and a coordinated optimal 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's demand for energy is increasing year by year, resulting in increasingly depleted primary fossil energy and increasingly serious environmental problems. To improve energy efficiency and reduce CO 2 Emissions, the realization of sustainable social development, and the combination of traditional energy systems and renewable energy power generation such as solar energy and wind energy have attracted more and more attention. and live. However, the microgrid is only limited to electric energy, and lacks the coupling and coordinated operation with various energy...
