Description

technical field [0001] The invention relates to the technical field of electric power economy, in particular to a multi-energy complementary capacity configuration method of a comprehensive energy utilization park. Background technique [0002] With the increasing proportion of new energy development, the basic characteristics of the traditional energy system have gradually changed. The comprehensive energy utilization park has broken the boundaries of the original different energy systems and realized the integration of various types of energy. The randomness and indirectness of wind, light, water, fire and other resources, as well as the complementarity of time and space, have brought challenges to the safe and stable operation of the power system. The rational allocation of the capacity of each energy source is to ensure the feasibility of a comprehensive energy park. The key is to improve the power supply reliability of the integrated energy system. Making full use of t...

Problems solved by technology

At present, the domestic capacity allocation of comprehensive energy utilization parks only stays in the multi-energy complementary capacity allocation of primary energy sources such as wind, light, water, and fire, and does not take into account the multi-energy complementary capacity allocation of secondary energy sources such as cold, heat, and electricity. Does not involve the configuration of electrical loads, heating loads, cooling loads, etc. on the user side in different seasons
