Using Electrification and Automation
Goal 17: Strengthen the means of implementation and revitalize the Global Partnership for Sustainable Development Corporate strategies can also contribute to a more sustainable society. For example, Phoenix Contact's gaining LEED Silver and Zero Energy certifications for its logistics center for the Americas was one part of the company's initial goal to achieve carbon neutrality at all of its worldwide locations. The company's next target is to create an entirely climate-neutral value-added chain before 2030. Conclusion The building sector is the most significant contributor to global CO 2 production. LEED and ZEB certifications are important
tools for measuring the success of using electrification and automation to create more efficient and sustainable buildings. As shown, large-scale PV generation installations integrated with on- site cogeneration capacity can contribute to a greener society. LEED-certified buildings also support achievement of the UN's seventeen SDGs and the goal of eliminating global poverty by 2030.

n Each PV string is monitored for current and voltage output. That data is evaluated to determine string health and possible maintenance needs. n Panel temperatures are monitored with numerous sensors spread throughout the installation.
LEED and sustainable development The United Nations (UN) has identified 17 Sustainable Development Goals 2 (SDGs) intended to end global poverty by 2030. According to the USGBC, the electrification and automation inherent in LEED buildings can contribute toward meeting 11 of the 17 SDGs, including:
n Weather conditions like wind speed and direction,
temperature, relative humidity, and air pressure are collected. n Solar irradiance is measured with two pyranometers, one at a 10-degree angle matching the installed angle of the panels and one installed horizontally. n Soiling sensors measure the light loss caused by dust and dirt on the surface of the PV panels. n Cameras provide security monitoring of the system. The system also needs data loggers and interfaces. For example, the company's Radioline wireless modules, like the model 2901541, communicate wirelessly with PV module temperature and soiling sensors using the RS-485 protocol without cables. In other cases, power over Ethernet (PoE) is used to transmit power and data at the same time. Intrusion protection can be provided by FL mGuard 1000 Series Security Routers, like the model 1153079, that provide firewall security and user management.

Tying it all together takes a controller like the DIN-rail mount model 1069208 from Phoenix Contact based on the company's PLCnext Technology (Figure 3). When paired with an input/ output (I/O) module like the model 2702783, the controller aggregates data from the sensor network and transmits it to a cloud service provider. In addition, an industrial PC runs Phoenix Contact's Solarworx software. The included software tools and libraries support communication protocols and standards the solar industry adopts. The system enables customized automation and visualization of PV system operation, and it's compatible with
third-party software packages that can analyze historical and real-time data for performance optimization. The libraries include functional blocks that meet the requirements
of IEC 61131 standard for programmable controllers.
Feed-in control is the final piece of the electrification puzzle for integrating distributed energy resources (DERs) like PV arrays with the power grid. PGS controllers from Phoenix Contact can monitor the voltage and reactive power levels at grid connection points and determine the required control values for the inverters to support feed- in management of power into medium- and high-voltage grids.
Goal 13: Climate action
