Dispatch Optimization Scheme for High Renewable Energy Penetration Using an Artificial Intelligence Model

Abstract

The scientific community widely recognizes that the broad use of renewable energy sources in clean energy systems will become a substantial and common trend in the next decades. The most urgent matter that has to be addressed is how to enhance the amount of renewable energy integration into the system while ensuring system stability in the presence of sudden fluctuations in generation and system faults. This study introduces a methodology that may be applied to any power system to optimize the level of renewable energy sources (RESs) integration. The methodology relies on using a trilayered neural network (TNN), which is a model utilized in the field of artificial intelligence. In order to apply and analyze the outcomes of the proposed optimization technique, the Kundur power system is employed as a case study. The objective of this methodology is to enhance the operation dispatches of a power system to attain a higher level of renewable energy output, specifically photovoltaic (PV) generation, while maintaining the stability of the system. This would enhance the stakeholders’ or utility providers’ capacity to make well-informed judgments on operation dispatch processes. The findings of this study suggest that it is generally recommended to raise the dispatchable power values for the generators in the loading region and lower the dispatchable power values for the generators in the generating area.
