Optimal utilization of load side power and heat resources based on aggregator mode

Abstract

Combined cooling, heating and power system (CCHP) can realize the cascade utilization of energy and improve the energy utilization efficiency. Focusing on the phenomenon that the traditional self-sufficiency mode is easy to cause insufficient or excess regional energy supply, considreing the complementarity between different regional load characteristics, an internal multi-region interconnected complementary energy supply method based on aggregator mode was proposed. In order to solve the problem of uncertainty in the optimal dispatching of multiple resources in the region under the aggregator mode, an optimal dispatching model based on interval linear programming was constructed, which took the minimum operation cost of aggregator as the objective function. The feasibility and effectiveness of the method are verified by analyzing the aggregator mode in residential area, commercial area, office area and industrial area. The results show that the operation cost can be reduced and the economic benefit can be improved under the aggregator mode.

Large-Scale Power Cloud Resource Scheduling Algorithm in an Edge Computing Environment

“…According to the existing power grid environment, power grid bandwidth and power grid availability, energy can design an efficient dispatching scheme. This method makes a good correspondence between the user's task requirements and the resources of the power cloud, so that the task requirements can be met to a certain extent and the security of the power grid can be ensured [19]. On this basis, the optimal scheduling scheme is determined by several evaluation criteria, and each resource scheduling system assigns each task to the corresponding resource node according to the mapping relationship.…”
