FAQS about Wind power generation technology patent card

What are the different types of wind energy patents?

These patents cover inventions related to ofshore wind energy, including key technology concept groupings such as: fixed and floating foundations, towers, mechanical power transmission, blades and rotors, hybrid systems, energy storage, and grids and submarine cables.

How do wind energy patents work?

Methodology for wind energy application can be generalized for patent searching to target other technology domains. Wind energy patents are conventionally defined using Cooperative Patent Classification (CPC) and International Patent Classification (IPC) codes that represent wind motors (F03D) and wind energy (Y02E 10/70).

How many patents are used in a wind energy application?

The number of patents used in all four samples on the wind energy application are outlined in Table C1. The sample size used for Sample 2 (Keyword Set – WEDD1) is 257, which is between 5 and 10% margin of error.

Do patent statistics reveal technological trends in the offshore wind supply chain?

This patent insight report on innovation trends in the offshore wind supply chain, jointly prepared by the European Patent Office (EPO) and the International Renewable Energy Agency (IRENA), assesses patent statistics to reveal technological trends in the offshore wind industry.

When did wind energy technology become a patented technology?

Following an initial phase marked by limited patent filings, the patenting activity in ofshore wind energy technologies experienced a notable surge starting in 2006. Subsequently, a period of consistent annual expansion persisted until 2012.

How many offshore wind energy patents are there?

The new report, which summarises the results of patent analyses in this field, found that about 17 000 offshore wind energy patent families were published between 2002 and 2022, at an average annual increase of 18%. While growth stagnated between 2014 and 2017, recent years have seen a sharp increase in filings.

Wind and energy storage combined power generation technology

The hybrid power generation system (HPGS) is a power generation system that combines high-carbon units (thermal power), renewable energy sources (wind and solar power), and energy storage devices. [pdf]

FAQS about Wind and energy storage combined power generation technology

What is a wind storage system?

A storage system, such as a Li-ion battery, can help maintain balance of variable wind power output within system constraints, delivering firm power that is easy to integrate with other generators or the grid. The size and use of storage depend on the intended application and the configuration of the wind devices.

Why is integrating wind power with energy storage technologies important?

Volume 10, Issue 9, 15 May 2024, e30466 Integrating wind power with energy storage technologies is crucial for frequency regulation in modern power systems, ensuring the reliable and cost-effective operation of power systems while promoting the widespread adoption of renewable energy sources.

What is energy storage system generating-side contribution?

The energy storage system generating-side contribution is to enhance the wind plant's grid-friendly order to transport wind power in ways that can be operated such as traditional power stations. It must also be operated to make the best use of the restricted transmission rate. 3.2.2. ESS to assist system frequency regulation

How is energy storage capacity allocated for combined wind-storage system?

An optimal allocation model of energy storage capacity for combined wind-storage system is studied. With the maximum total system revenue as the objective function, the influencing factors and their sensitivities of the energy storage capacity allocation of the combined system are analyzed.

Why do wind turbines need an energy storage system?

To address these issues, an energy storage system is employed to ensure that wind turbines can sustain power fast and for a longer duration, as well as to achieve the droop and inertial characteristics of synchronous generators (SGs).

Can energy storage control wind power & energy storage?

As of recently, there is not much research done on how to configure energy storage capacity and control wind power and energy storage to help with frequency regulation. Energy storage, like wind turbines, has the potential to regulate system frequency via extra differential droop control.

[pdf]

FAQS about Technology used in Japan s solar power generation

Can solar energy be used in Japan?

To maximize the use of solar energy and overcome those drawbacks, two promising technologies have been developed: space-based solar power (SBSP) and next-generation flexible solar cells. Japan is making steady progress toward the practical implementation of both.

What percentage of Japan's Energy is solar?

In 2022, solar energy accounted for 5.39% of Japan’s total energy mix and 9.91% of its electricity generation. In both cases, solar power in Japan holds the largest share of all renewable sources. This is a drastic contrast to even a decade ago when solar energy contributed less than 1% of the country’s energy.

Why is solar power growing in Japan?

The steady growth of solar power in Japan is attributed to several factors, including the country’s focus on energy security, economic efficiency and environmental sustainability. Post-Fukushima, there was a national reevaluation of energy sources.

Who makes solar power in Japan?

In line with the significant rise in installations and capacity, solar power accounted for 9.9% of Japan's national electricity generation in 2022, up from 0.3% in 2010. Japanese manufacturers and exporters of photovoltaics include Kyocera, Mitsubishi Electric, Mitsubishi Heavy Industries, Sanyo, Sharp Solar, Solar Frontier, and Toshiba.
