Abstract

The invention discloses a multi-energy complementary optimal scheduling method and system for an integrated energy system, and the method comprises the following steps: obtaining the operation data and parameters of the integrated energy system; establishing a multi-energy complementary optimization scheduling model of the integrated energy system by taking the minimum equipment operation cost as a target; constructing constraint conditions of the multi-energy complementary optimization scheduling model of the integrated energy system; under constraint conditions, solving an optimal solution of the multi-energy complementary optimization scheduling model of the integrated energy system; and performing multi-energy complementary scheduling on the integrated energy system by taking the optimal solution as a scheduling scheme. According to the invention, main operation equipment in the integrated energy system is selected, an objective function and a constraint condition which take the minimum daily operation cost of the equipment as an objective are constructed, a 0-1 variable is introduced to carry out linearization processing on part of the objective function and the constraint condition, and an established optimization model is changed into a mixed integer linear programming model, so that the solving speed is improved, and a reference basis is provided for solving the operation cost of the comprehensive energy system.

Description

Technical field [0001] The present invention belongs to the field of integrated energy, and more particularly, relates to an integrated energy system pluripotent complementary scheduling method and system optimization. Background technique [0002] Energy and the environment is an important material basis for the development of human society to survive, people's livelihood and national security at stake. At present, human energy is dependent on fossil fuels, but is facing increasing depletion of fossil fuels is not only dangerous, but also a large number of fossil fuel use caused environmental problems are being seriously hampered the development of coordination between our economic, energy and the environment. Traditional grab and rely on non-renewable resources, growth can not sustain economic and social development, petroleum and coal as the core of fossil energy era coming to an end, we will be faced with new energy and fossil energy complementary "hybrid energy era."
