Distributed Optimization for Optimal Control in Distribution Power Systems
Electric utilities have always used a centralized optimization approach for optimal planning and operation of distribution power systems. These often include minimization of generation costs (Economic Dispatch), flexible load control or Demand Response (DR), minimization of substation and active power demand (Conservation Voltage Reduction) etc. However, with more and more distributed energy resources (DERs) being integrated to power grid, the AC optimal power flow (ACOPF) problem has now become a large scale optimization problem. This is due to inclusion of DER power injections as additional system variables and DERs' inverter operational constraints as additional system constraints to the OPF problem. Utilities are hence looking towards a distributed solution approach due to their improved scalability, flexibility, robustness and higher computational speed.
The presentation will include these topics-
1. Why are we shifting towards distributed optimization for optimal control in power systems?
2. Why is ACOPF problem formulation and its solution is hard?
3. Need for relaxations and approximations in ACOPF problem.
4. A brief summary on distributed optimization.

GPS Spoofing Attack in Power Systems
Spoofing the GPS receiver in PMUs, also known as the time synchronization attack (TSA) can have adverse effects on various power system applications which are dependent on synchrophasor measurements. The GPS is used to synchronize the time stamps of PMUs across their disparate geographical locations, due to which PMUs become susceptible to spoofing attacks. These attacks are generally carried out by generating a fake signal of higher strength than the authentic GPS signal, and the fake signal is then locked on to by the GPS receiver of the PMU. This presentation will discuss how a test set up was developed to create real-time spoofing of GPS clock using actual field equipments. The presentation also addresses the effect of a GPS spoofing attack on the frequency and rate of change of frequency (ROCOF) of the power system, evaluated when there is a certain transient in the system leading to eventual load shedding. The impact of the attack on the load shedding scheme is also assessed.
