The analysis of security of electricity supply (SoES) is particularly complex due to, among others, the liberalisation process and the increasing penetration of renewable energies. Larsen et al. (2016) propose a framework based on twelve dimensions to evaluate SoES for a single jurisdiction. However, actions aimed at improving one dimension might impact others negatively, adversely affecting the overall system. Understanding how these dimensions are interrelated is thus a prerequisite for appropriate planning and resource allocation. We apply a Cross Impact Analysis (CIA) to these twelve dimensions to determine the degree to which the different dimensions depend on each other. From this we derive an influence diagram to visualise the interdependencies and a scatter plot to categorise the dimensions as independent, driver, connector or outcome. The connecting dimensions are the central elements of the feedback mechanisms of SoES, reinforcing or balancing the effect of other dimensions. Actions targeting the dimensions categorised as drivers or connectors are potentially the more effective ones a regulator can take, as the consequences will gradually ripple through the system. They affect systemwide performance, but not necessarily in the desired direction. Having an integral view of the dimensions' interdependencies provides a better understanding of the higher-order changes an intervention may cause. This enables policymakers and regulators to identifying where in the system to intervene to achieve the desired effect with the least amount of resources and with as few undesirable side-effects as possible.

“…National power transmission systems generally have high reliability and many have some level of design redundancy. Nevertheless, the generation and distribution of electric power incurs significant individual and population exposure: Large power stations are bespoke designs as are large transformers (Sobczak & Behr, 2015), and transmission networks may face significant "resilience" issues (Carvajal, Serrano, & Arango, 2013;Sidhu, 2010). Liquid fuels can be stockpiled at national level, and to a lesser extent locally, however the level of stockpiling is limited -and even the higher levels of stockpiling are likely to be small compared to the time to rebuild a major production plant (terminal, or refinery).…”

The ancillary services are essential in the power Systems operation, historically this services haven’t been regulated in any way in Honduras. There have been changes recently into the regulatory framework in the entire electricity sector alongside the large-scale injection of photovoltaic and wind powered centrals in the System. Considering these scenarios, the ancillary services become a necessity in terms of the operation for the power system and the stability associated with it. In this paper, we analyze the technical and economic aspects related to the frequency control, voltage control and blackstart services, we compare the services provided in different countries and how it is possible to adapt the successful cases to the Honduran power system.
