How VSC-HVDC is used in offshore wind farms?
With the popularization of VSC-HVDC in offshore wind farms, the frequency adjustment strategy for the control system has become a critical factor to improve stability, and frequency compensation for the power system can be achieved through variable speed fan and VSC control station .
How Chinese offshore wind power system is developing?
Research and development about large scale of offshore wind turbine generator system are rapidly advancing. The developing trends of Chinese offshore wind power are large-scale turbines, deep-water construction and intelligent management. New technologies for offshore wind power generation are to be further studied.
How many offshore wind power plants are there in Guangdong?
According to The Guangdong Offshore Wind Power Development Plan issued by Guangdong Provincial Development and Reform Commission, the province has 23 planned sites with a total installed capacity of 66.85 GW, and about 30 GW of installation is anticipated to be put into operation by 2030 .
Which countries build the most wind power in 2024?
Germany (4 GW) built the most new capacity last year, thanks to its rapid ongoing onshore wind expansion. After Germany, the UK (1.9 GW) and France (1.7 GW) built the most new capacity. All three countries installed new capacity onshore and offshore. The capital raised for new wind projects in Europe was €33bn in 2024.
How much wind power does Europe have in 2024?
Europe installed 16.4 GW of new wind power capacity in 2024. The EU-27 installed 12.9 GW of this. 84% of the new wind capacity built in Europe last year was onshore. 2.6 GW of new offshore wind power capacity was connected to the grid. Europe now has 285 GW of wind power capacity, 248 GW onshore and 37 GW offshore.
How much wind power will Europe install in 2025?
The EU-27 accounts for 231 GW of the total installed capacity, 210 GW onshore and 21 GW offshore. We expect Europe to install 187 GW of new wind power capacity over 2025-2030. The EU-27 should install 140 GW of this – 23 GW a year on average. This would bring total installations in Europe and the EU to 450 GW and 351 GW respectively by 2030.

This topic presents the communication flow between the 5G base station (gNB) and user equipment (UE) nodes, explaining the uplink (UL) and downlink (DL) transmission.
FAQs about UE and base station communication process
How does a base station work?
Figure 3.5: Base station establishes one or more tunnels between each UE and the Mobile Core's User Plane. Fourth, the base station forwards both control and user plane packets between the Mobile Core and the UE. These packets are tunnelled over SCTP/IP and GTP/UDP/IP, respectively.
What is a user equipment (UE)?
User Equipment (UE) User Equipment (UE) refers to the end-user devices, such as smartphones, tablets, or IoT devices, that connect to the 5G Radio Access Network (RAN) for wireless communication. The UE communicates with the network infrastructure through the base station, which serves as the access point for wireless connections.
How does a wireless UE work?
First, each base station establishes the wireless channel for a subscriber's UE upon power-up or upon handover when the UE is active. This channel is released when the UE remains idle for a predetermined period of time. Using 3GPP terminology, this wireless channel is said to provide a bearer service.
How does a UE node transmit a BSR?
The UE node transmits a BSR with a predefined periodicity as an out-of-band packet. You can use the connectUE object function of the nrGNB object to set the periodicity of the BSR report. Scheduling grant — Upon receiving the BSR from the UE node, the base station provides grants (an out-of-band packet) to the UE node for the UL transmission.
What is a baseband unit (BBU)?
Baseband Unit (BBU) The baseband unit (BBU) plays a vital role in transmitting data from the RAN node to the core network and relaying data received from the core network to the radio unit for further transmission.
What is ul data transmission?
UL data transmission — This is an in-band packet. The UE node transmits the UL data over the physical uplink shared channel (PUSCH) when it receives the scheduling grant. This figure illustrates the DL transmission. The DL transmission consists of these packets. CSI reference signal (RS) — The gNB node sends CSI-RSs to the UE node.
