- Development operation algorithm of EMS
The operation algorithm of EMS is divided into Load Agg, REG Agg and ESS Agg by type of target resources. Because the overall objective of EMS operation is participation into energy market, basic objective function of each EMS is enhancement of profit for both EMS operator and resource owner.

- Development interoperability technology of each EMS
Develop interoperability technology between each EMS to operate more efficient EMS and maximize profit. Interoperable technology can increase economic value when participating in trading platform. For this, analyze the available operation scheme for each configuration such as Load – ESS or REG – ESS. Judgment on whether each configuration is possible follows the economic value and the rules of the current electricity market. Finally, we derive the interconnection plan and calculate expected profit according to each combination.
