Application of meta-heuristic techniques to engineering optimization problems has proved to be an efficient tool. In transaction based electricity markets transmission losses must be allocated among transactions rather than the individual buses as in case of pool based markets. In this paper an attempt is made to apply Music Based Harmonic Search Algorithm (MBHSA) for the allocation of transmission losses among transactions in electricity markets. Transmission loss can be easily allocated among transactions using the values of transaction coefficients. In the proposed method optimal values of transaction co-efficients are found as an optimization problem using MBHSA. Proposed method is tested with IEEE 24 bus reliability test system with multiple transaction sets and the test 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.

Fair allocation of transmission loss among market participants is essential in the present restructured electricity markets. This paper proposes a direct method to find the loss allocation. The methodology is based on simple circuit laws and does not involve any assumptions. Considering the real power injection and real power loss contribution factors loss allocation can be done. Case study of the proposed loss allocation methodology is conducted on an IEEE 14 bus system. Results are compared with the results of the existing methods in the literature.

“…Most of the proposed conventional theories based on sensitivity analysis cannot deal with the nonlinear aspect of the problem, and the sum of the allocated losses results in twice the loss [4]- [10]. Recently, many studies have been conducted based on various approaches such as circuit theory [11]- [13], game theory [14], integration method [15]- [17], etc [18], [19]. This paper shows that the total transmission loss can be represented by the sum of the bus-wise partial integration calculated by real power injections.…”

-This paper presents a new algorithm to determine accurate bus-wise transmission loss allocation utilizing path-integrals dictated by the transaction strategy. For any transaction strategy, the total sum of the allocated transmission losses of all buses is equal to the actual loss given by the AC powerflow calculation considering the distributed slack. In this paper, the bus-wise allocation of the transmission loss is calculated by integrating the differential loss along a path determined by the transaction strategy. The proposed algorithm is also compared with Galiana's method, which is the well-known transmission loss allocation algorithm based on integration. The performance of the proposed algorithm is evaluated by case studies carried out on the WSCC 9-bus, IEEE 14-bus, New England 39-bus, and IEEE 118-bus systems. The simulation results show that the proposed algorithm is fast and accurate with a large step size.
