Remote control of photovoltaic power plants: enhanced optimization and security

Introduction

Photovoltaic solar power plants play a key role in the energy transition. However, to maximize their performance and ensure continuous production, the operators of these installations must meet several challenges: the real-time supervision of equipment, the management of remote incidents, and the optimization of production costs, especially in times of negative prices. ALEMCA stands out as an indispensable solution, offering centralized management of IT and network infrastructures, remote control of equipment and optimization of operations in a secure environment.

Complementarity with energy supervision tools

‍

In solar photovoltaic power plants, operators are already using supervision solutions to optimize production and manage business processes. ALEMCA integrates perfectly with these systems by providing an additional layer for the management of network infrastructures, telecommunications, IT and automatons. Solutions such as S4E, Epice, SolarID, Bazefield, or even tools developed in-house, are often used to monitor energy production. Meanwhile, ALEMCA ensures that connectivity, data transmission and remote access to equipment are secure and continuous.

In addition to guaranteeing a reliable network infrastructure and complies with safety standards such as NIS2 directive, ALEMCA is distinguished by its ease of use. Unlike other complex solutions, it allows supervisors and maintainers — who are not necessarily IT technicians — to easily access remote equipment. Thanks to a intuitive interface And a simplified access management, users can oversee critical infrastructures and intervene quickly without the need for in-depth technical skills.

This synergy between ALEMCA and energy supervision tools not only allowsimprove operators' operational efficiency, but alsoensure continuity of service, essential for maintaining optimal production levels.

Remote control for the management of negative rates

‍

One of the major challenges for operators of solar photovoltaic power plants is the management of negative rates. When there is overproduction of electricity on the grid, prices can become negative, which means producers have to pay to put their electricity into the grid. In these situations, it is crucial to be able to reduce or stop production quickly and automatically to avoid financial losses.

Thanks to ALEMCA, operators can remotely control all the automatons or inverters of their power plants for adjust production depending on market conditions. For example, when a negative rate is forecast, teams can program the reduction of production or the temporary stoppage of certain segments of the power plant. This remote control can be automated to react in real time to market fluctuations, thus offering a maximum flexibility to operators.

In addition, ALEMCA allows Broadcast orders simultaneously to a large number of power plants, thus facilitating the management of negative tariffs on a large scale. This feature not only guarantees a increased reactivity, but also a simplified management complex situations that might otherwise require costly and time-consuming manual intervention.

NIS2 security and compliance

‍

Like any energy infrastructure, solar power plants must meet strict security requirements. Cyber threats are a growing reality, and operators must protect their infrastructure intrusion reviews. ALEMCA integrates a Zero Trust approach (ZTNA), ensuring access segmentation and secure management of remote connections.

For example, when an external technician intervenes to maintain an inverter, ALEMCA allows him to be granted a temporary and restricted access only to the equipment concerned, without exposing the rest of the plant. This fine access management reduces the risk of compromise, while ensuring compliance with regulations such as the NIS2 directive.

Cost reduction and production optimization

‍

In addition to the management of negative rates, ALEMCA allows significantly reduce operating costs solar power plants in limiting interventionss on site. Thanks to remote access, technical teams canmonitor and intervene on equipment in real time, which considerably reduces the need to physically move around the installations. This represents a significant savings, especially for power plants located in remote or hard-to-reach areas.

For example, in the event of an inverter or a datalogger failure, ALEMCA makes it possible to diagnose and resolve the problem remotely, thus avoiding the immediate dispatch of a technical team. This ability to intervene remotely not only optimizes failure managements, but it also guarantees a continuous equipment performance, while minimizing travel costs.

In addition, ALEMCA makes it possible to remotely manage certain regular maintenance tasks, such as the Updating the firmware of the inverters Or the reconfiguring systems depending on production conditions. En extending the life of equipment And in automating maintenance operations, operators can reduce long-term costs while maximizing the efficiency of their power plants.
