Methodology for optimal bus placement to integrate wind farm optimizing power flows

Abstract

This paper proposes an alternative algorithm to locate the optimal bus placement to integrate wind farms based on the criterion of minimizing the electrical losses using the solution of the power flow problem to identify the best connection point. The wind farm is modeled as a negative load being possible to connect this power generation to the possible connection buses and obtaining the power flow solution for each different connection point as a generation change or displacement. The IEEE 14, 30 and 57 bus test systems have been used to validate the proposed methodology. The results have shown the optimal bus among a possible set of them that causes minimum losses when a wind farm is integrated to it.Keywords-losses; negative load; point of common coupling; power flow; wind farm integration; wind power generator.

Optimal Installation of Wind Turbines to Minimize Energy Losses

“…The last iteration ends when the above procedure is repeated for all buses and converges when the difference between the total losses in an iteration and the previous one is less than the specified tolerance (Souza, 2005). To insert Wind Turbines (WT) as generators in the calculation of the power flow, the negative load concept was used in order to indicate their ability to supply power to the system (Molina-Moreno et al, 2015).…”

“…Due to the increase in the number of Wind Farms (WF), it is necessary to connect them at suitable locations in the system, as this connection point influences the stability of the power system and the power quality. WF should preferably be connected to a reference bus, so as not to affect the stability of the electrical system (Molina-Moreno et al, 2015). The intermittent nature of the wind has resulted in technical and economic challenges with largescale integration.…”

Optimal Inverter-Based Resource Installation to Minimize Technical Energy Losses in Distribution Systems

“…I NVERTER-based Resources (IBRs), e.g., wind, photovoltaic (PV), and battery energy storage systems (BESS), have become attractive solutions with the increased demand and the need to reduce carbon emission in power generation. The IBRs are an alternative to meet the demand due to the low investment risk and short installation time, as they are located close to the loads and have a low occupation of physical space, allowing their installation in large load centers [1] [2]. However, the connection of IBRs results in several technical and economic challenges due to the intermittent nature of wind, irradiance and temperature.…”
