TL;DR: A cost-based reactive power pricing is proposed, which can integrate the reactive power cost minimization and the voltage security problem into the optimal power flow (OPF) problem, and the sequential quadratic programming (SQP) is employed to solve the optimization problem.

TL;DR: In this article, the authors proposed a market-based reactive power ancillary service management scheme to tackle the challenge of reactive power procurement and settlement issues in the power supply industry, where the total minimum reactive cost is separated into two components: one is assigned to the generation side while the other to the loading side.

TL;DR: In this article, an OPF based reactive power optimization model along with a power flow tracing based method is proposed to tackle the problem of separating reactive power support for a generator has two components: one for supporting its own real power transmission and the other for supplying reactive demand, improving system security, and controlling system voltage.

TL;DR: In this article, a centrally-managed reactive power market model is adopted in which the system operator, taking into account the technical feasibility and economic efficiency, procures the required reactive service from the competitive reactive power suppliers and the incurred cost is fully allocated to all users.

TL;DR: In this paper, a reactive power optimization model along with a power flow tracing based method is proposed to tackle the problem of reactive power ancillary services and reactive power markets have attracted attention from researchers and system operators all over the world.
