Query: s-Vector Control of Battery Energy Storage System: Definition and
  Application   We give the definition of s-Vector control by using the complex power vector
in the p-q plane to quantify the feasible operational region of battery energy
storage system (BESS) and to find the optimal power set-point solution. The
s-Vector control features in the avoidance of using costly optimization solvers
to solve optimization models online which is also an execution time bottleneck
in real-time control. The advantages of s-Vector control are fast and stable
computational efficiency. We validate a s-Vector based real-time controller of
BESS to provide frequency response and voltage support as ancillary services
for the power grid. The objective is to maximize the utility of the BESS asset.
We formulate the dynamic capability curve of the DC-AC converter and the
security requirements of the battery cells as constrains of the control system.
The initial power set-points are obtained based on the traditional droop
control approach. Based on s-Vector control, a fast optimization solution
algorithm is proposed to find the optimal power set-point and guarantee the
security. According to the experimental validation in our 720 kVA / 560 kWh
BESS on EPFL campus, we achieve 100 ms of refreshing the real-time control
loop. As a benchmark, using optimization solver requires 200 ms to update the
real-time control loop.
