In the existing multi-period
robust optimization method of active and reactive power coordination in
distribution networks, the reactive power regulation capability of distributed
generators (DGs), operation costs of regulating equipment, and the current of
shunt capacitance of cables are not taken into account. In this paper, based on
branch flow equations, a multi-period two-stage mixed integer second-order cone
programming (SOCP) robust optimization model of active and reactive coordination
in distribution system with cables is developed considering the reactive power
regulation capability of DG, action costs of switched capacitor reactor (SCR),
on load tap changer transformer (OLTC), energy storage system (ESS), and
current of shunt capacitor of cables. Further, against to the deficiency of low
computational rate of column and constraint generation method (CCG), a novel
method iteratively solving the first and second stage model on cutting plane is
proposed. In the first stage model, the number of variables and constraints
keeps constant during the iteration. In the second stage model, it only needs
to solve the model of each single time period. Then their results are
accumulated. Thus, the computational speed using the proposed method is much
higher than CCG. The effectiveness of the proposed method is separately validated
on the 4-bus, IEEE 33-bus, and PG69-bus distribution systems.
