Embodiment Construction

[0038] Such as figure 1 As shown, the steps of the distributed energy cloud networking intelligent control method in this embodiment include:

[0039] 1) Obtain the output demand, load demand, and optimal electricity price curve from the superior dispatching center, and the optimal electricity price curve includes output electricity price information and load electricity price information at different times of the day;

[0040] 2) According to the optimal electricity price curve, 24 hours a day is divided into different time periods, and the output demand and load demand dispatched by the superior dispatching center are allocated to each energy subnet according to the time period, and the energy subnetwork in different time periods is obtained. optimal distribution of output or optimal distribution of loads, the energy sub-network includes power generation equipment, energy storage equipment, power consumption equipment and charging piles;

[0041] 3) For each energy sub-netw...

Abstract

The invention discloses a distributed energy cloud networking intelligent control method and a distributed energy cloud networking intelligent control system. The distributed energy cloud networking intelligent control method comprises the steps of: acquiring an optimal electric price curve, dividing time periods, allocating optimal allocation output or optimal allocation load to energy subnet at different time periods, controlling power generation equipment to generate power according to the maximum output for each energy subnet, and charging charging equipment when the charging equipment plugs into a charging pile; and controlling energy storage equipment to adjust actual output and actual load of the energy subnets. The distributed energy cloud networking intelligent control system comprises a central scheduling decision-making unit, an energy cloud networking allocation unit and a distributed decision-making execution unit. The distributed energy cloud networking intelligent control method and the distributed energy cloud networking intelligent control system achieve the effects of reducing excess load and output surplus by taking the energy subnets as a unit based on controlling the controllable loads such as the energy storage equipment in the energy subnets and the charging pile, achieve the purposes of power grid load balancing, peak shaving and load shifting, can prevent charging of various kinds of large-scale charging equipment from affecting peak of the power grid, achieving efficient / optimized configuration of energy resources, and enhance social and economic benefits.

Description

technical field [0001] The invention relates to electric power dispatching technology, in particular to an intelligent control method and system for distributed energy cloud networking. Background technique [0002] Power system dispatching is an effective management method adopted to ensure the safe and stable operation of the power grid, reliable external power supply, and orderly progress of various power production tasks. Power system scheduling is a complex system that provides power from many power plants and supplies power to users through transmission, transformation, distribution, and power supply networks. Its production, supply and sales processes are simultaneously completed and balanced in an instant. Therefore, its scheduling tasks are different from general industrial production scheduling. Power system dispatching must maintain the balance of power generation and load at any time, requiring each department within the dispatching jurisdiction to complete dis...
