Energia-alan suljettujen järjestelmien käytönvalvonta on murroksessa, ja kyberturvallisuus vaatii aiempaa enemmän panostusta. Kokonaispalvelukonsepti VALVOT kattaa käytönvalvontajärjestelmän suunnittelun, toteuttamisen ja ylläpidon kyberturvallisesti.

January 13, 2010 – Efran Ibrahim, Technical Executive at the Electric Power Research Institute, engages the rapidly evolving discussion around the Smart Grid by separating core issues involved in system development and implementation from abundant hype and speculation, a perspective based on his experience with EPRI’s seminal Intelligrid program.

But adding more solar and wind power here, as elsewhere, brings its own problems. In particular, it challenges the grid’s stability and resilience. The power systems that most people are connected to were designed more than a century ago. They rely on large, centralized generation plants to deliver electricity through transmission and distribution networks that feed into cities, towns, homes, schools, factories, stores, office buildings, and more.

Our 100-year-old power system wasn’t intended to handle power generators that produce electricity only when the sun is shining or the wind is blowing. Such intermittency can cause the grid’s voltage and frequency to fluctuate and spike dangerously when power generation isn’t balanced with demand throughout the network. Traditional grids also weren’t designed to handle energy flowing in two directions, with hundreds or thousands of small generators like rooftop solar panels attached to the network.
