COOPERATIVE CONTROL STRATEGY FOR DISTRIBUTED WIND STORAGE
The role of the energy storage system cooperative control device
The coordination controller, which regulates virtual inertia values by using technique for order preference by similarity to ideal solution (TOPSIS) evaluation algorithm, is proposed to adaptively adjust the inertial output capability of each VSG unit and provide optimized dynamic frequency support to the grid.

How does energy storage control work?
This control method avoids circulating current between different batteries and effectively prevents overcharging or deep discharging of the batteries. Each energy storage device cooperatively shares loads under different initial states of SoCs and ESS capacities instead of directly driving all HESSs output power consensus. 1. Introduction
Is active power control necessary in a wind-storage combined system?
It is necessary to ensure the cooperative operation of the wind generators (WGs) and energy storage devices. Since active power control is necessary in a wind-storage combined system (WSCS), there is a lot of research on this aspect. So far, most of the control methods proposed in the literature are centralized , , , , .
What is a battery energy storage system?
Based on these studies, electrochemical storage (battery storage) is the most commonly used technique and covers many applications. The battery energy storage system (BESS) is apower electronic-based device that can minimize the power variation in the system and increase the integration of RESs through a suitable cooperative control .
How does a storage unit control the output power of a converter?
Using this control strategy, the storage unit with the highest SoC provides more power to support the load, while the unit with lower SoC provides less power. Thus, the output power of each converter will beproportional to each SoC. The method is validated using simulation results from PSCAD/EMTDC software. Previousarticlein issue
How does state of charge affect a distributed energy storage device?
When installing distributed energy storage devices in the distributed WFs, the state of charge (SoC) is a key parameter that affects the operational life of the ESSs. The imbalance of SoC might result in early termination of charging or discharging and accelerate battery degradation , .
How do energy storage devices achieve power-sharing between ESSs?
Under the premise of different capacities of energy storage device, the method derives the power compensation for each ESS through the difference values between the load demand and the total wind output power to preliminarily achieve power-sharing between ESSs.
Laos wind solar and storage integrated project
The Northern Laos Interconnected Clean Energy Base is a pivotal power supply project supporting electricity interconnectivity between China and Laos. It aims to develop an integrated large-scale clean energy base incorporating wind, solar, biomass, and other renewable sources. [pdf]FAQS about Laos wind solar and storage integrated project
Are there wind projects in Lao PDR?
Despite the target of 73 MW via the Renewable Energy Development Strategy, there are currently no operational wind projects in the Lao PDR.
Will Laos expand its solar power base in 2024?
In 2024, a Chinese state-owned power company signed an agreement with Laos to expand a wind and solar energy base in the north of the country. Laos, a mountainous country, has produced about 80 per cent of its electricity from hydropower over the last decade but has struggled to scale up its solar and wind power.
Does China have a power plant in Laos?
In 2022, China Western Power signed a supply and service deal worth US$409 million with another power company in Laos. In 2024, a Chinese state-owned power company signed an agreement with Laos to expand a wind and solar energy base in the north of the country.
Are electricity exports a key part of Laos' development strategy?
Electricity exports have formed a key part of the development strategy of landlocked Laos. PHOTO: REUTERS BEIJING - Laos has signed a US$1.45 billion (S$1.94 billion) clean energy deal with a Chinese power plant equipment manufacturer as the South-east Asian country furthers its push into clean power generation and transmission.
Who is China Western power industrial & Xekong thermal power plant?
China Western Power Industrial, along with a Singapore-based construction company, signed the agreement with Xekong Thermal Power Plant in Laos to design, supply, and build a 1,800-megawatt clean energy power project in southern Laos, according to a stock exchange filing by the Sichuan-based company on March 24.
