In this article commonly known concepts are analyzed regarding their suitability for the German transmission system. Therefore, an approach for the analysis was developed and exemplary results are given using this approach. Under consideration of the overall system, the concepts of reducing losses in combination with minimizing(n-1)-warnings or-indications^1 as well as the sole minimization of(n-1)-warnings and-indications are the most reasonable approaches. However, under grid security aspects best results can be achieved by reducing operational limits and therefore, by the minimization of(n-1)-warnings.展开更多

This risky situation calls for a new security concept, one that transcends traditional state centrism, national supremacy and coercion. The new security concept, which should assimilate the general theory of grand strategy,focuses on a vision that spans time and space, valuing humankind as it exists as one of the dynamic factors of nature and society. The essentials of the new security concept are to recognize balanced development as the substance of security and to govern national strength and the application of means and tactics. It aims at realizing comprehensive security across various social fields within states, to achieve mutual security among national, international and individual actors, as well as harmony between man and nature, continuous security leading to lasting and universal peace in the future.展开更多
