Robust optimal scheduling method for micro-energy network with complementary cooling, heating and electrical energy

Abstract

The invention discloses a robust optimal scheduling method for a micro-energy network with complementary cold, hot and electrical multi-energy, comprising the following steps: step 1: building a micro-energy network coordination scheduling model; system, air supply system, heating system and cooling system; Step 12: Build a coordinated scheduling model of the micro-energy network: Consider the thermal inertia of the heating system and the cold inertia of the cooling system, and introduce an index to evaluate the thermal comfort of the indoor environment to control the indoor environment Heating, with the goal of minimizing the operating cost, establish the coordinated dispatch model of the cold, hot, electric and multi-energy complementary micro-energy grid including P2G devices in the island / grid-connected mode; Step 2: Solve the coordinated dispatch model of the micro-energy grid: The uncertainty of photovoltaics is described by the expected value and the fluctuation interval, and the robust linear optimization theory is used to realize the deterministic transformation of the stochastic optimization model, overcome the dependence on the probability distribution of random variables, and obtain a robust peer-to-peer model for the coordinated scheduling problem of the micro-energy grid. .

Description

technical field [0001] The invention belongs to the technical field of electric power systems, in particular to a robust optimal scheduling method for a micro-energy network with multi-energy complementary cooling, heating and electricity. Background technique [0002] With the increasing depletion of traditional fossil energy and environmental problems such as global climate change, the energy industry is constantly undergoing changes. Clean, efficient and sustainable energy development and utilization mode is an important development direction in the future energy field. American scholar Jeremy Rifkin put forward the concept of energy Internet in "The Third Industrial Revolution", believing that the industrial model of large-scale utilization of fossil energy is gradually coming to an end, and predicted that the combination of new energy technology and Internet technology The energy internet will promote the rise of the third industrial revolution. In recent years, the En...
