The intelligent networking of power-generating and energy-consuming sectors enables an efficient and balanced overall system. 2 Phoenix Contact

From fossil fuels to renewable energies Focusing on solar power From a technical point of view, a complete global energy revolution is considered to be possible. The concepts for the energy revolution and the technologies required for this are already known. The energy revolution is focusing on photovoltaics due to its high availability and high level of acceptance. The targeted expansion of photovoltaic systems in Germany is 200 GW of installed photovoltaic capacity by 2030. To achieve this goal, new photovoltaic systems with a capacity of around 150 GW will be needed over the next eight years. This is roughly equivalent to an area of 170,000 ha of photovoltaic systems. To put this in perspective, this could vastly cover an area the size of the city of London. In Europe as a whole and worldwide, there are also ambitious expansion targets for renewable energies. The goal is to accelerate the reduction of climate damage caused by conventional energy sources and, above all, to produce electricity at low cost. Menteroda solar park, Germany 4 Phoenix Contact

Connect distributed generation plants to the grid faster The challenges facing feed-in management Decentral power generation plants need to play their part in ensuring high grid stability. The system yield, storage, and self-consumption must be regulated and monitored. Linking various energy sources, using types of storage, and shifting loads to meet the peak generation are the major tasks for meeting the energy needs in the near future. The accelerated expansion of renewable energy is creating increasing challenges for grid and system operators, electricity marketers, and consumers alike. This includes limited grid capacities, poor grid compatibility, inadequate grid security management, an increased bidirectional power flow, and cybersecurity.

Solutions for feed-in management and stable power grids Feed-in management can handle a large portion of these challenges. The controllers at the grid connection points record the existing voltage and the reactive power. With the Power Control Unit (PCU) from Phoenix Contact, you can implement reliable feed-in management. We offer freely programmable interfaces and function blocks and constantly work towards meeting the requirements for comprehensive energy management systems. PLCnext Security The PCU is based on our PLCnext Technology and was designed in line with security-by-design criteria. The development processes are certified in accordance with IEC 62443-4-1. Some of the key security measures include the use of a Trusted Platform Module (TPM), a configurable Linux kernel, and the use of the Linux firewall, plus the implementation of a crypto store for certificates and keys. Certified in four EU countries Continuously extended compatibilities High availability Maximum flexibility Multi-instancing Q@Night control Industrial quality Multi-instancing Multi-instancing of the PCU makes it possible to control different power generation plants independently and simultaneously at one grid connection point, for example a combination of a photovoltaic system and a CHP plant. Currently, up to three different types of plants can be controlled with one PCU. Open control technology and pre-programmed PCU functions Our PCU can be customized specifically to your application. The interfaces to the grid operators, power providers, direct sellers, and energy measuring devices are to be connected by the user on the basis of the specific project. In addition, we offer a wide variety of controller functions for controlling all kinds of distributed power generation plants.

Certified solution In April 2016, the Network Code on the Requirements for Generators (NC RfG) became effective in Europe. This network code regulates the conditions for connecting electricity generators at all voltage levels. Mandatory throughout all of Europe, it focuses on trading electricity across borders and regulations including, for example, capabilities for frequency support and the provision of reactive power. Each European country defines this directive in more detail in order to apply it in its own national context. Since May 2018, the NC RfG has been applied at the national level in Germany. Phoenix Contact is one of the first manufacturers to have certified its PCU for the German market since 2019. Since then, this certificate in accordance with VDE-AR-N 4110/20 has been applied successfully in Germany for systems above 135 KW. The strong growth in the solar market has spread to all of Europe. Phoenix Contact is aiming for PCU certification for countries where a certified solution is possible. The first three European countries where this is the case are Spain, Poland, and the Netherlands. Starting in May 2022, Phoenix Contact will provide component certificates for the PCU for these countries. This will make commissioning and connection to the grid much easier and mark a new milestone in accelerating the expansion of renewable energies in Europe.

References and services Agrivoltaics, Germany Q@Night control, Germany PV park management, Portugal The agrivoltaic system protects the berries underneath from adverse weather conditions. Our feed-in controller not only handles the grid-compliant feed-in but also receives weather data, such as the intensity of the sun’s rays. Together with ASG Engineering GmbH, we implemented the Q@Night control function in a 10 MW photovoltaic system in the Dessora Industrial Park in Germany. Our intelligent feed-in controller regulates the reactive power of the photovoltaic system even at night. Phoenix Contact has equipped 195 MWp in six Portuguese photovoltaic systems with its integrated park management. Our solution not only acquires data, performs monitoring, and collects weather data. It also regulates the feed-in at the grid connection point.
