SYSTEM FOR MANAGING DISTRIBUTED ENERGY RESOURCES AND METHODS FOR MANAGING DISTRIBUTED ENERGY RESOURCES

Abstract

The invention relates to a system for managing distributed energy resources and a method for managing distributed energy resources, wherein the system for managing distributed energy resources analyzes the optimization problem to minimize or maximize the cost index of distributed energy resources into a main problem with linear constraints and a subproblem with non-linear constraints, the optimization problem is generated from information on system connections, information on interconnected busbars on distributed energy resources, and information on means on distributed energy resources acquired from the system for managing energy resources.The distributed energy management system estimates new constraints for the main problem based on sensitivity information from the dual problem of the subproblem, adds new constraints to the main problem's constraints to limit the search area for the main problem's solution, and calculates the range of output combinations of distributed energy resources. The distributed energy management system also solves the optimization problem defined as the main problem based on the range of output combinations to calculate the power generation amounts of the distributed energy resources, and provides the calculated power generation amounts to the energy resource management system.
