PIER Program Long-Term Priorities
As a "proof-of-concept" program, EISG seeks out concepts that are not yet proven and are very early in the research pipeline: so early that even angel investors may not yet be willing to invest. The EISG program encourages technical innovation and risk taking. Since the EISG program focuses on innovative concepts at the very early stage of development, the goal is to uncover a few good ideas and start them on the path of development, leading to ratepayer benefits and the development of new technologies that will benefit the California economy. Following are suggested research topics for several PIER areas of public interest RD&D.
Energy Systems Integration
- Technologies to facilitate grid connection for distributed generation.
- A testable method to aggregate loads and DG into a collected resource with the demand sensing and cognizant control for effective demand response systems.
- Technologies to enhance real time information about grid conditions with the goal of optimizing the use of existing transmission assets.
- Grid dispatch using probabilistic criteria. Applicants should use actual data to demonstrate feasibility.
- Sensors and controls for fast detection of high voltage/high current system faults and response devices.
- Speed the accuracy and response time of grid dispatch and control.
- Technologies to enhance the robustness of the grid during major stress events.
- A testable method to un-bundle and assess the cost and value of the services provided by the grid. The method and the test of its feasibility must be contained within the same grant application.
