Task or service user, for example when the energy of device cluster output is unable to satisfy user demand, leaf node refers to according to node control
It enables and present energy state between supply and demand, the timely energy flow for adjusting neighbouring device group meets user demand.
(3) to the working condition of the father node of leaf node notice device cluster, so that the father node of leaf node can be known
The working condition of equipment in itself controllable second range indirectly controls equipment by control leaf node realization, most
Eventually so that device cluster can more preferably complete task or service user.
Two, the function of any one intermediate node:
(1) any one intermediate node is by directly controlling the child node of intermediate node, to indirectly control in the second range
All devices work so that device cluster can complete task or service user.
(2) working condition of the equipment in the second range is reported to father by any one intermediate node (claiming first node afterwards)
Node (claims second node) afterwards, so that second node would know that the working condition of all devices in itself controlled range,
And control of the adjustment to the child node of second node, it is final so that device cluster can more preferably complete task or service user.
Three, the function of root node
(1) reach the mesh of all devices in control distributed energy resource system by directly controlling the child node of itself
, so that device cluster can complete task or service user.
In summary, the control system of distributed energy resource system is realized and is divided in such a way that classification does not control in layer
The control of cloth energy resource system, so that distributed energy resource system realizes a certain or certain functions.In addition, since classification does not control
Distributed energy resource system, the node of each node control and/or the negligible amounts of equipment, this will be avoided as far as possible because at node
Reason resource is limited and leads to not the case where controlling child node or equipment appearance, controls distributed energy with this control system
The efficiency of system is higher.
