“…Coordination of these VAr controllers between cases and satisfaction of all security constraints simultaneously are of course time-consuming and difficult. On the other hand, the optimal power flow approach (OPF) has become widely used for the reactive power problem [1,2,3,8,10,11,13]. The coordination between all reactive power controllers is achieved via OPF in a single case.…”

The short term (one day) scheduling of VAr controllers involves the setting of shunt compensators, EHV taps and generator voltages. A decomposition approach is presented to solve the problem of optimal short-term scheduling of shunt compensators in this paper. The entire problem is decomposed into two levels: the master and the slave levels. The master level deals with minimization of the depreciation cost of compensators in order to reduce the control actions for compensators while satisfying operating constraints. The slave level treats minimization of capitalized MW losses while satisfying system security constraints by adjusting generator voltages and taps. These two levels interact through linear constraints in the iteration process. The IEEE 30-bus and a practical 265-bus systems, namely Taiwan Power System, are used to serve as samples to show the applicability of the presented approach.

“…However, the most critical aspect of Newton ' s algorithm is that the active inequalities are not known prior to the solution and the effi cient implementations of the Newton ' s method usually adopt the so -called trial iteration scheme where heuristic constraint enforcement/release is iteratively performed until acceptable convergence is achieved. In [56,59] , alternative approaches using linear programming techniques have been proposed to identify the active set effi ciently in the Newton ' s OPF. In principle, the successive QP methods and Newton ' s method both using the second derivatives, considered a second -order optimization method, are theoretically equivalent.…”

The generation of offshore wind power is less predictable. This can cause the overload of offshore DC transmission system and thus requires the curtailment of wind power. To reduce the amount of wind power curtailment, a method of optimising DC power flow using DC power flow controller (DC-PFC) is proposed. The analytical expression of coordinating DC-PFCs and converters in controlling the power flow of the DC system has been created. Method has been developed to optimise the power flow of DC grids within which control setting changes automatically in different wind conditions to reduce both the power curtailment and power losses. The proposed method has been demonstrated and validated on a 9-port DC system. It is concluded that both the curtailment of wind power and power losses are effectively reduced by inserting DC-PFCs into DC grids.
