“…This process is repeated for each hour over a billing cycle, for example, 1 month. So, the penalty, which should be imposed on each HS in a billing cycle (APs); is calculated using Equation (10).…”

“…In a restructured power grid with proper information and data, monitoring and control platforms, the grid voltage quality can be improved by the implementation of an economical mitigation solution such as the appropriate algorithm for the pricing of the harmonic contamination [8,9]. Due to the widespread use of non-linear loads, the use of real-time methods in data analysis has become very important for analysing the harmonic voltage data to real-time monitor and control the system [10,11]. For many countries, subscribers with low power factors are charged [12], so non-linear loads can receive a penalty determined according to their contribution to the harmonic voltage [13,14] or other indices such as harmonic adjusted power factor or service quality index [15].…”

Improving network power quality through harmonic reduction requires recognition of Harmonic Sources (HSs) to drive them to compensate their harmonics. This paper proposes a new method for equitable distribution of the Harmonic Compensation Cost of the network among the HSs based on the Harmonic Contribution Matrix. Each element of the Harmonic Contribution Matrix is the harmonic contribution of a specific source to the harmonic voltage of a specific bus. The output of the proposed method is a penalty curve for each HS over time. The amount of the fine estimated for each individual HS per hour is a function of not only the contribution of that HS to the harmonic voltage of different buses, but also the contribution of the Harmonic Compensation Cost from the perspective of each bus, nominal voltage of each bus, and the sensitivity of each bus to the harmonic voltage. The proposed algorithm is evaluated on the IEEE 14-bus network and Esfahan regional electrical power network in Iran. The simulation results demonstrate the capability of the proposed method to allocate the hourly penalty curve to the HSs.
