Restructuring of power industry made loss allocation among market participants to be an important task especially in view of bilateral and multiple transaction framework. This paper presents a new Z bus based method for allocating transmission losses among multiple transactions. Real power loss is expressed in terms of real power injections and the transaction amounts. Using the base case converged load flow solution, real power transmission losses are allocated among the transactions. Proposed method is tested with 3 bus system and IEEE 24 bus reliability test system with multiple transaction sets and the results are compared with the existing technique in the literature. The method can also be extended for reactive power loss allocation if reactive power transactions are generated according to the real power transaction amounts.

“…The amount of losses dependents mainly on the size of the country, the length of power lines, voltage of transmission and distribution, and quality of network (complexity, technology that is used, and the particular conditions that prevail in the various regions and countries). This impact in transactions is important and several schemes have been proposed so far for the allocation of losses [29][30][31][32][33].…”

SUMMARYTransmission operators and regulators face the enormous challenge to meet both the request for a high-performing grid as well as the public's concern about the burdens of electric power transmission. Although huge infrastructural projects for the development of interconnections are at several stages, the associated transmission burdens are not yet fully incorporated in the respective socioeconomic analysis. In this respect, the aim of this paper is to present a collective summary of electricity transmission burdens and their associated impacts. To increase coherence, the burdens have been classified in the following categories: transmission losses; electromagnetic fields; infrastructure; visual intrusion; noise; interruption of supply; land use; ecosystems; and property values. Moreover, the burdens relation with transmission technologies and associated impacts are illustrated in original overview tables.

“…In [25], an attempt is made that the difference between the sum of theoretically allocated losses and the actual system loss are reduced. In [26][27][28][29][30][31][32] the concept of distributed slack bus is introduced. In this method loses allocated to busses are exactly equal to actual loss which is given by ac power flow.…”

Abstract:In deregulated power systems, the transmission loss allocation plays a key role in planning and designing of the power system. In practice, these losses should be allocated to both generators and loads depending on the amount of contribution in the total power system losses. In this paper, a new methodology to optimally allocate the transmission losses to either generators or loads based on the power flow tracing methodology is presented. In this methodology, trace usage coefficients are formulated to allocate transmission losses. In real time, system operator tries to minimize the transmission losses to increase the security of the system. In this paper, for the sack of analysis, the formulated OPF problem with transmission losses as objective is solved while satisfying system constraints using gravitational search algorithm. The minimized transmission losses are then allocated to either generators or loads. The proposed methodology is tested on standard IEEE-30 bus and real time Indian-24 bus test systems with supporting numerical results.
