Method for optimizing operation of regional integrated energy system taking into account load aggregator

Abstract

The invention discloses a method for optimizing the operation of a regional integrated energy system considering a load aggregator, First, the day-ahead forecasting data of electric load and day-aheadforecasting data of cold and heat load of the regional integrated energy system are obtained, Load aggregators obtain their respective regional integrated energy system heating and cooling loads taking into account the demand side response according to the specified different demand side response plans, In order to minimize the total operating cost of the regional integrated energy system, network constraint, energy production and conversion equipment constraints, As that constraint of the energy storage equipment and the cold-thermoelectric power balance of the regional integrated energy system are the constraint condition, an optimization model is established to obtain the operation power planning of each energy supply equipment and energy storage equipment, and the operation planning cost under each demand side response plan is compared to determine the optimal load aggregator demand side response plan and the optimal operation planning of each energy supply equipment and energy storage equipment. The method of the invention can effectively improve the economy of the operation of the regional integrated energy system.

Description

technical field [0001] The invention relates to the field of multi-energy complementary modeling optimization of power systems, in particular to a method for optimizing the operation of regional comprehensive energy systems based on load aggregators. Background technique [0002] In the field of new energy, there is a situation of synergistic optimization of different energy forms. In the process of development and utilization of each energy, it needs the synergy and complementarity of multiple energy sources to achieve efficient utilization. However, due to the differences in the development of different energy systems, most of them are independently planned, designed, and operated independently. The lack of mutual coordination will lead to low energy utilization, poor overall security and self-healing capabilities of the energy supply system. With the continuous development of smart grid technology, the decentralized energy market and energy network structure make the trad...

However, a large number of different types of distributed loads are dispatched at the same time, which is not only difficult to form a scale effect, but also difficult to dispatch

[0003] In the current research results, although there are many expansions on the demand side response to the modeling of the regional integrated energy system based on the energy hub model, the expansion of the market mechanism of the demand side response based on the load aggregator and the temperature-controlled load aggregator Multi-functional complementary, there is still no relevant public report
