SHENZHEN, China, March 9, 2020 /PRNewswire=KYODO JBN/ --

Over the next 5 to 10 years, renewable energy will assume a more prominent role as

a main power source for power grids. Solar power, in particular, as the most noteworthy

form of renewable energy, has a particularly bright future. However, as renewable represents

a greater proportion of total energy production, ensuring safety, reliability, and cost-effectiveness

across power generation assets will become the upmost priority.

With the rapid development of emerging ICT technologies, such as AI, cloud, big data,

and 5G, and in full consideration of the latest trends in power electronics technology,

Huawei has engaged with experts in the field and has released 10 emerging technical

trends for smart PV in 2025. These trends encompass four dimensions: lower levelized

cost of electricity (LCOE), power grid friendliness, intelligent convergence, and security

and trustworthiness. The trends aim to drive the industry toward intelligent, green solutions,

and provide insight into innovation and soaring growth in the new energy industry.

Trend 1: Digitalization

Huawei Predicts 10 Trends in Smart PV for 2025

Key point: More than 90% of global PV plants will be digitalized.

Despite the booming global PV market, there are still many dumb devices in PV plants,

from power generation to communications. These devices cannot be effectively monitored,

nor can they provide fault alarm. With the rapid development of digital technologies such as

5G and cloud, it is expected that more than 90% of PV plants will be fully digitalized by 2025,

making it possible for PV plants to be simple, intelligent, and efficient management.

Trend 2: AI-driven Smart Upgrades

Huawei Predicts 10 Trends in Smart PV for 2025

Key point: Over 70% PV plants will apply AI techniques.

The in-depth integration of AI and PV will facilitate mutual sensing and interconnection

between devices, and will improve power generation and O&M efficiency through

collaborative optimization. AI techniques can offer promising new avenues for PV systems,

including: proactive identification and protection of PV module and device faults with AI

diagnosis algorithms; tracker algorithm optimization with massive plant data and self-learning

for  higher yields; and AI-aided solar-storage synergy to automatically optimize PV-storage

plant revenue. As LCOE continues to decrease and O&M complexity increases, AI techniques

will be highly likely to widely apply in PV plants.

Trend 3: Unmanned PV Plants

Huawei Predicts 10 Trends in Smart PV for 2025

Key point: More than 80% of the work in PV plants will be unmanned.

With the ascendance of AI and the Internet of Things (IoT), intelligent products and

services will bring convenience to the whole PV solution. With integrated expert experiences

and continuous self-learning, AI will be widely deployed to replace O&M experts in many

diagnostic and decision-making functions. Drone inspection and robot-based automatic

O&M will handle dangerous and repetitive O&M work that requires a continual high degree

of accuracy, for enhanced productivity and safety in PV plants. As is estimated, it is expected

that PV plants in the future will be fully unmanned.

Trend 4: Proactive Support for Power Grids

Huawei Predicts 10 Trends in Smart PV for 2025

Key point: PV plants will shift from grid-adapting to grid-supporting.

The increasing penetration level of power-electronic-interfaced energy will undermine power

grid strength, hindering the broader application of PV systems. Over the next 5 years,

PV plants must gradually evolve from adapting to the power grid, to supporting the power grid.

To this end, inverters should possess capabilities such as wide short circuit ratio (SCR) adaptability, capability to control harmonic current within 1%, consecutive high/low voltage

ride-through, and fast frequency regulation, which are necessary for grid connection.

Trend 5: Solar + Storage

Huawei Predicts 10 Trends in Smart PV for 2025

Key point: The proportion of PV systems coupled with energy storage will exceed 30%.

With the greater penetration of new energy sources, power grids will have increasingly

stringent requirements for frequency regulation and peak shaving. In the meantime,

battery costs are decreasing with technology advancement. It is projected that energy

storage will work in tandem with PV systems, and become a critical component.

Projections indicate that by 2025, the proportion of PV systems with energy storage will

exceed 30%.

Trend 6: Virtual Power Plants

Huawei Predicts 10 Trends in Smart PV for 2025

Key point: More than 80% of residential systems will connect to Virtual Power

Plant (VPP) networks.

Over the next 5 years, ICT technologies, such as 5G, blockchain, and cloud

services, will be widely applied in distributed power plants, forming VPPs for

collaborative management, and participating in the scheduling, transaction, and

auxiliary services for power systems. The development of VPP technology will

inspire new business models and attract new market players in distributed PV

scenarios, serving as an engine of growth for distributed PV.

Trend 7: Active Safety

Huawei Predicts 10 Trends in Smart PV for 2025

Key point: Arc-fault circuit interrupter (AFCI) will become a must-have feature in distributed

PV rooftop systems, and will be incorporated into international industry standards.

With the broader application of distributed PV, building and personal safety

has become a major concern. PV arcing risks caused by the poor contact of nodes

in PV modules, poor connections from PV connectors, or aged or broken cables,

have become a pressing matter in the industry. To mitigate such risks, AFCI

will become a standard function for distributed PV rooftop systems, and will be

incorporated into international industry standards.

Trend 8: Higher Power Density

Huawei Predicts 10 Trends in Smart PV for 2025

Key point: Inverter power density will increase by more than 50%.

With the trend of lower LCOE of solar, there calls higher requirements in

higher power of a single module and easy inverter maintenance. To achieve this,

higher power density is required. With breakthroughs in research of wide-bandgap

semiconductors, such as SiC and GaN, as well as advanced control algorithms,

inverter power density is expected to increase by more than 50% in the next 5 years.

Trend 9: Modular Design

https://photos.prnasia.com/prnh/20200309/2743935-1-i

Huawei Predicts 10 Trends in Smart PV for 2025

Key point: Core components such as inverters, PCS and energy storage devices

will adopt modular design.

Inverters, PCSs, and energy storage devices are key components in a PV plant,

which greatly affect the availability of the entire PV plant system. As the capacity

and complexity of PV plants increase, the traditional, expert-driven approach for

onsite maintenance will be too costly. Modular design will become mainstream,

as it enables flexible deployment, smooth expansion, and expert-free maintenance,

greatly reducing O&M costs and improving system availability.

Trend 10: Security and Trustworthiness

Huawei Predicts 10 Trends in Smart PV for 2025

Key point: Security and Trustworthiness has become a necessary requirement for

PV plants.

The increase in the cumulative capacity of global PV plants, and greater

complexity of network architecture, which makes the network security risks of

PV plants increasing. In addition, there are more stringent requirements for

user privacy and security for distributed PV plants. All these trends suggest

that PV plants need to possess security and trustworthiness capabilities in

terms of reliability, availability, security, safety, resilience, and privacy.

Our common desire to explore as human beings, knows no limits. We are always

looking to soar to new heights, plunge to deeper depths, and seek out new truths.

The convergence of 5G, cloud, and AI technologies is shaping a world where everything is

sensed, connected, and intelligent at a speed faster than we think. By listing the top 10

trends for the PV industry for 2025, Huawei hopes to play its part in inspiring the creation

of a green, intelligent world, in which the boundless potential of new energy solutions can

be broadly shared across society.
