Abstract

Grid Architecture not only provides valuable new insights into grid modernization planning and design, but also provides the means to future-proof technological investments and to reduce integration costs – two issues that concern regulators and utility executives alike. Proper structure creates intrinsic grid characteristics that bolster resilience, capability, and affordability, and help safeguard investments by limiting change effects. Well-planned grid structure simplifies downstream decisions and frees up architects and engineers working on individual components or systems to employ creativity with assurance that unintended consequences will not crop up to hamper or even invalidate their work. For these reasons, it is not just important, but crucial, that the structural issues addressed by Grid Architecture be considered before other aspects of grid modernization are undertaken.
