Optimal Ensemble Control of Loads in Distribution Grids with Network Constraints. (arXiv:1710.09924v1 [cs.SY])
来源于:arXiv
Flexible loads, e.g. thermostatically controlled loads (TCLs), are
technically feasible to participate in demand response (DR) programs. On the
other hand, there is a number of challenges that need to be resolved before it
can be implemented in practice en masse. First, individual TCLs must be
aggregated and operated in sync to scale DR benefits. Second, the uncertainty
of TCLs needs to be accounted for. Third, exercising the flexibility of TCLs
needs to be coordinated with distribution system operations to avoid
unnecessary power losses and compliance with power flow and voltage limits.
This paper addresses these challenges.
We propose a network-constrained, open-loop, stochastic optimal control
formulation. The first part of this formulation represents ensembles of
collocated TCLs modeled by an aggregated Markov Process (MP), where each MP
state is associated with a given power consumption or production level. The
second part extends MPs to a multi-period distribution power flow opti 查看全文>>
