1. Continuous-time Economic Dispatch and Optimal Automatic Generation Control
- Developed a new economic dispatch method that schedules generation for continuous time and a new automatic generation control method that considers economic optimality of generators during real time control. The combined method improves the economic and dynamic performance of secondary and tertiary frequency control.
2. A Novel Hierarchical Frequency-Based Load Control Architecture:
- An ARPA-E funded project under the NODES (Network Optimized Distributed Energy Systems) program done at Northwestern University along with the partners Argonne National Laboratory, Schneider Electric, and OPAL-RT Technologies. We developed a frequency-based load control architecture to provide additional frequency response capability and allow increased renewable generation in the power grid.
3. Demand Response and Consumer Behavior:
- Developed price based distributed demand response methods such that efficiency loss due to selfish behavior of consumers measured by price of anarchy can be minimized,
- Developed incentive-based demand response with self-reported baseline mechanism to reduce baseline inflation.
4. Renewable Aggregation and Cost Allocation Based on Cost Causation:
- Developed aggregation strategy for a collection of renewable energy resources bidding in a two-settlement market
- Allocated joint deviation cost based on cost causation principle.
5. Sharing Photovoltaic Solar Cells and Batteries:
- Developed successful cooperation strategies among agents sharing solar cells and batteries under various billing mechanisms.
6. Incentive Design in a Distributed Problem with Strategic Agents:
- Designed incentive in a distributed multi-agent system with a central operator where the operator does not have a direct control over the agents, the agents have interdependent utility functions, and the utility function of the operator is not necessarily the sum of the utility function of the agents.
7. Numerical Methods in Optimal Control:
- Designed algorithm for minimization of norm of a controller to bring a dynamical system from a given initial state to a given end-point constraint set in a finite time interval,
- Designed algorithm for maximizing the duration of open loop operation of a perturbed linear time invariant system, while keeping the performance error within bound.
