In a groundbreaking development for the energy sector, researchers have proposed a novel approach to optimize the operation of virtual power plants (VPPs) within intelligent distribution networks. The study, led by Mohabbat Vafa from the Department of Electrical Engineering at the Khomeinishahr Branch of Islamic Azad University, was recently published in the journal *Nature Scientific Reports*.
VPPs are innovative systems that aggregate various energy sources, storage devices, and responsive loads, operating as a unified entity within power distribution networks. The key to their success lies in the ability to control active power and, through electrical inverters, manage both active and reactive power exchange with the grid. This capability opens up new avenues for financial gains in various energy markets.
The research introduces the concept of a “coupled virtual energy” (CVE), which integrates VPPs with electric inverters to participate simultaneously in energy, active (flexibility), and reactive (reactive power) service markets. “By optimizing the operation of CVEs, we can maximize profits in these markets while enhancing the overall functionality of the distribution network,” explains Vafa.
The study employs a deterministic formulation to achieve this optimization, constrained by AC optimal power flow equations and the operational model of CVEs. To address uncertainties in energy prices, renewable energy generation, and mobile storage device energy consumption, the researchers applied an adaptive robust optimization (ARO) approach. This method ensures that the CVE’s objective function—maximizing profit in each market—is met despite these variables.
One of the most significant aspects of this research is its potential to revolutionize energy efficiency across various sectors. “The proposed design can be applied in industrial, agricultural, and residential consumption areas, leading to increased energy efficiency and significant financial benefits for power sources, storage devices, and responsive loads,” Vafa notes.
The study’s findings were validated through numerical results obtained from implementing the scheme on an IEEE 69-bus intelligent distribution network (IDN). The results demonstrate the feasibility and potential of the proposed approach, paving the way for future developments in the field.
This research not only highlights the importance of integrating VPPs with electric inverters but also underscores the need for adaptive robust optimization to navigate the complexities of modern energy markets. As the energy sector continues to evolve, such innovations will be crucial in achieving greater efficiency, reliability, and profitability.
The study, “Robust operation of renewable virtual power plant in intelligent distribution system considering active and reactive ancillary services markets,” was published in *Nature Scientific Reports*, a prestigious journal known for its rigorous peer-review process and high-impact research. This publication underscores the significance of the findings and their potential to shape the future of the energy sector.
