Virtual Power Plants and the Rise of Sustainable Energy Solutions

In the contemporary era, rapid technological advancements are not only enhancing people's lives through innovations like the Internet of Things and smart homes but also significantly increasing the demand for energy in societies worldwide. Electricity, a fundamental driver of global economic development and individual well-being, has experienced a substantial surge in demand over the past decade. This heightened demand has put significant pressure on power grids and the global environment. Simultaneously, many nations, in alignment with the goals of the Paris Agreement, have committed to annual greenhouse gas reduction targets, underscoring the critical role of Distributed Energy Resources (DERs).

?DERs, encompassing a wide range of renewable energy sources and energy-efficient technologies, have gained growing prominence in national energy strategies due to their vast potential, minimal environmental impact, and sustainability. Supported by governmental initiatives, the robust development and deployment of DERs for both residential and commercial use have become evident on a global scale.

The Evolution of Distributed Energy Resources (DERs)

Distributed power generation, exemplified by Distributed Energy Resources (DERs), has attracted significant attention and undergone rapid advancements owing to its numerous advantages in terms of reliability, economics, and flexibility. The shift in energy resources is unmistakably leaning toward clean and decentralized energy conversion methods.

Despite the evident advantages of distributed energy, characterized by its stochastic and variable nature, it does introduce challenges related to grid stability and reliability. These challenges encompass phenomena like fluctuations in energy supply, line congestion, voltage variations, and harmonic effects. Furthermore, the economic viability of current grid-connected generation projects can be hindered by the nascent stage of the technology and associated high costs.

Over the years, the energy landscape has witnessed a transformation driven by the transition toward cleaner and more distributed energy resources. In this evolving scenario, Distributed Energy Resources (DERs) are progressively assuming a pivotal role in supporting the power grid and actively participating in electricity markets. When a substantial number of controllable DERs and high-capacity loads are integrated into the grid, their collective functionality can rival that of traditional centralized power generation methods. This is where the concept of Virtual Power Plants (VPPs) enters the stage.

History

The concept of Virtual Power Plants was originally introduced by Awerbuch and Preston in 1997, albeit without a precise definition. The rapid evolution of VPPs has led to various interpretations in academic literature, often viewed from diverse angles that encompass Distributed Energy Resources within energy management.

VPPs have been portrayed as trading platforms for DERs in wholesale market contract scenarios in one study, while another depicts them as DER aggregators, exerting control over DER output within the network. Furthermore, VPPs have been characterized as ICT systems responsible for managing DERs, fluctuating loads, and energy storage. They can also be conceptualized as a cluster of power plants, unifying DERs, controlled loads, and storage assets, with an EMS serving as the central control hub.

Concurrently, VPPs encompass a wide array of DERs distributed across various voltage levels within the distribution network, offering flexibility and optimization capabilities that contribute to resource adequacy.

Market Size and Growth

?Virtual Power Plants (VPPs) are rapidly emerging as a pivotal force within the energy sector, garnering substantial adoption from utilities, aggregators, and the information and communication technology industry. This growing interest stems from significant advancements in enhancing the resilience and robustness of power systems, especially in the context of peak demand response. The VPP market is poised for remarkable growth, with a projected Compound Annual Growth Rate (CAGR) of 21.3% from 2020 to 2027. This growth trajectory is expected to catapult the market from its 2019 valuation of USD 1.3 billion to an impressive USD 5.9 billion by 2027.

?

Moreover, on a global scale, the VPP market is set to reach a value of $1,187.5 million by 2023, underscoring the increasing significance of VPPs in the energy landscape. This trend is not just a momentary surge but is anticipated to be a persistent force shaping the future of the industry.

The Role of Virtual Power Plants

?Virtual Power Plants represent one of the most practical and potent solutions for effective power management. They achieve this by merging embedded technologies and communication networks into power systems. VPPs foster close cooperation and interaction among participants by facilitating a bidirectional flow of energy and offering real-time monitoring and energy conservation capabilities. This approach empowers consumers to directly participate in energy markets by trading surplus electricity at favorable prices without the need for intermediaries.

?

For small DER installers, VPPs offer the opportunity to sell excess energy to the market, as the scheduling algorithm maximizes the utilization of surplus energy. Simultaneously, consumers without DERs or energy storage can actively engage with the VPP by implementing load-shifting, peak shaving, and valley-filling strategies. In addition to these benefits, VPPs play a crucial role in enhancing network security through optimized operational scheduling, ensuring compliance with energy management regulations.

?

Economic and Societal Benefits

?From a utility perspective, the use of Virtual Power Plants yields significant cost savings. In a direct comparison with alternative solutions, VPPs demonstrate a compelling advantage in terms of utility system costs. It is estimated that a VPP can ensure resource adequacy at approximately 40% less cost than a natural gas peaker plant and 60% less than a battery-based solution.

?

According to insights from the Rocky Mountain Institute (RMI), the United States has the potential to deploy a staggering 60 gigawatts (GW) of VPP capacity by 2030. By extrapolating from the experiences of utility systems, such an expansion could effectively address future resource adequacy requirements while saving an estimated $15 billion to $35 billion over the next decade, as compared to alternative energy solutions.

?

Furthermore, it's essential to recognize that these savings are exclusive of the broader societal benefits that arise from decarbonization and enhanced resilience. Over the same ten-year period, consumers can anticipate accruing an additional $20 billion in societal benefits derived from these advantages.
