“…So, to make the method more reliable, the proposed method is modified, but with only minor computation. In the modified method, the LMP difference is multiplied by the power flow through the line, which is nothing but the congestion rent in the line in base case (14). It is then divided by the total congestion rent to form an index (15).…”

“…LMP is generally composed of three components, a marginal energy component (same for all buses), a marginal loss component and a congestion component. The decomposition of nodal spot price obtained from OPF into three components is described in [14]. The derivation of nodal spot prices applying the first order optimality condition to Lagrange function (8) is derived in [15].…”

“…The real and reactive power prices are decomposed into the generation cost and the transmission losses [50,51]. The optimal reactive power dispatch, in terms of optimal allocation and generation of reactive power required by the load centers, is based on the real-time operating conditions [52,53].…”

This paper presents a novel optimization algorithm for the multi-area multi-fuel economic-emission dispatch problem and total power loss objective. The proposed method uses the uniform distribution to determine the control parameters and employs a two-stage initialization process. This enables various objectives to be optimized under practical constraints and device limits. We formulate a realistic generation cost that includes the cost of reactive power generation, shunt power injections, and total power losses, along with the conventional active power generation cost. A novel objective based on the concept of multi-fuel emissions makes the problem more realistic, and a generalized unified power flow controller (GUPFC) is considered. A detailed power injection model is developed for a GUPFC with two series converters, including switching losses of converters. A nondominated sorting methodology and particle swarm optimization algorithm are then used to solve the multi-objective problem on the standard IEEE-30 bus and real-time Indian-124 bus test systems.Keywords GUPFC power injection model · Multi-fuel active power cost · Multi-fuel reactive power cost · Multi-fuel emissions · GUPFC installation cost · NSUDTPSO

Abstract-Financial transmission rights (FTRs) are complementary to the locational marginal pricing of energy. The basic aim of the FTR mechanism is to guard forward contracts from uncertain congestion charges. FTRs are also useful to individual generators and loads for selling and buying power, respectively, at the prices of other locations. The concept has evolved, encompassing many features such as a simultaneous feasibility test, various ways to conduct auctions and allocations and secondary trading. FTRs also have a close relation to market power and transmission investment. This paper reviews most of the landmark research papers on the evolution of the FTR concept. It reports a comprehensive assessment of various facets of FTRs and allied issues. Financial transmission rights and flowgate rights (FGRs) are compared. The concept of long-term FTRs is discussed. The paper also touches upon future proposals in this area.
