IEC61850 Certified Computers - Empowering Security for Digital Substation
The convergence of automation and security stands as a cornerstone in the evolution of digital substations, which has enhanced efficiency, reliability, and performance. However, the proliferation of digital solutions also introduces new challenges, particularly in ensuring the robust security of critical infrastructure.
Utility institutions today are operating globally and relying on substation automation systems to have a secured and reliable solution for controlling and monitoring status of the substations and grids. Historically, substation automation structures involve multiple proprietary protocols which consist of numerous remote thermal units, PLCs, HMIs and plenty of computing systems to be wired together. This implementation usually results in heavy hardware investment, high engineering development time and high maintenance costs due to wiring redundancy and customized communication protocols. In fact, there could be compatibility issues among the automation devices from different vendors.

To reduce carbon emission, renewable energy has become one of the most discussed subjects regarding utilities. Among these, solar energy is the most anticipated source of renewable energy. In fact, many countries have already implemented solar PV plants in communities, commercial areas and industrial zones.

Traditionally, industrial control systems (ICS) like SCADA used to be isolated for its sole purpose of performing mission-critical tasks and controlling the processes within important infrastructures such as oil refinery, power plants, manufacturing factories, water/sewage treatment and energy plants. Therefore, these systems are built with conventional structures and operate in multiple decades of lifespan. However, with the increasing complexity in hardware design and the implementation of open network due to convenience and cost-effectiveness, ICS environments are vulnerable towards cyber threats. There have been incidents of cyber attacks over the past few years and thus ICS security has presented a great challenge. The following will discuss the issue in details and introduce robust platforms that can act as a gateway controller in packet inspection, whitelisting and protocol filtering.

The mounting concerns for climate changes have had many governments seek out feasible energy solutions that are more environmental friendly and less exhaustible; one of the more popular and better developed renewable energy solutions is the solar energy and the reason being solar power systems convert readily available and inexhaustible sunlight directly into electricity with solar cells, leaving almost no carbon footprint.
In order to strike the right balance between maintaining the most reasonable cost and ensuring the strictest facility management, system automation is usually depended upon for facility monitoring and process control. The key for successful substation management therefore lies in establishing efficient communications between control centers and off-site automation systems.

The global energy shortage is now a global crisis. And actions such as energy substitution are being taken to avoid the serious social and economic implications such crisis could potentially bring. Governments around the world have been tackling the energy shortage by implementing technologies to tap into renewable energy sources such as solar and wind power. However, such technologies, when compared to the more conventional power generation solutions, are far from cost-effective. Therefore more emphasis is now being placed on energy conservation and how it can be achieved. In order to conserve energy in an immediate and large-scale manner, most governments have drawn and put into effect energy and power related regulations to not only encourage effective energy usage with incentives but also to discourage wasteful energy consumption with penalties.

Wind power is a renewable source of energy and China has been actively expanding its wind installations over the past decade. Presently, China is the leader in wind power capacity, making up over 26% of the world total. Wind farms can consist of several hundred wind turbines in remote, harsh environments. Researchers believe that, with China’s land mass and long coastline providing the necessary wind resources, all of its electricity can come from wind power by 2030.
