Succès de la conformité nerc grâce à une approche de la communauté d’entreprise
mai 6, 2024
Alors que les services publics travaillent souvent dans des silos techniques, les auditeurs NERC sont formés pour vérifier les preuves de conformité et les données entre les normes interdépendantes. Le travail en silo mène souvent à des situations par inadvertance où les preuves de conformité d’une norme sont utilisées, mais incompatibles avec l’information produite ou utilisée par d’autres normes. Pour assurer l’atteinte des objectifs de déclaration des preuves de conformité dans chaque norme et exigence applicable, il est important de déterminer les interrelations et de créer un cadre où les experts en la matière (PME) de toutes les disciplines techniques tiennent compte des exigences en matière de cohérence des données probantes. Les auditeurs de conformité nerc sont également formés pour examiner les flux de processus et identifier s’ils sont complets ou incomplets. Les vérificateurs déterminent la pertinence de l’information en examinant la qualité et l’exhaustivité des preuves de conformité. Examiner la pertinence, la validité, l’uniformité et la fiabilité des éléments probants utilisés pour atteindre les objectifs de fiabilité de la vérification et appuyer leurs constatations et conclusions. Si des éléments probants contradictoires sont trouvés, ils l’identifieront dans les conclusions officielles de leur rapport de vérification de l’entité régionale (ER), ce qui pourrait entraîner une violation de la conformité et des amendes connexes. Afin d’améliorer la probabilité de résultats favorables de la vérification de la conformité de la NERC et d’éviter la nécessité de mettre en œuvre des plans d’atténuation, les contributeurs individuels et les PME devraient examiner certaines preuves de conformité réticulées pour assurer l’uniformité entre les approches utilisées pour consigner les preuves de conformité. Cela permettra à une entreprise de consacrer plus de temps à l’exécution des tâches de fiabilité de base et d’améliorer les obligations réglementaires de l’entreprise. Évitez d’attendre que les vérifications de conformité des ER soient en cours pour identifier les situations de preuves contradictoires.

octobre 25, 2022
The North American Electric Reliability Corporation (NERC) recently released an Inverter-Based Resource (IBR) Strategy, which details the steps needed to successfully integrate IBR facilities into the planning and operation of the power system. The strategy was put in place due to the rapid interconnection of IBR systems, which are extensively used for solar and wind generating facilities, including new battery-based energy storage systems and are one of the most significant drivers of power grid transformation. Because of control system inconsistencies, IBR facilities pose well-documented risks to power system reliability when this strategy’s practices are not adhered to. NERC’s plan calls attention to the need for thoughtful integration of IBRs and identifies current and future work required to mitigate reliability risks resulting from the deployment of this technology.

La NERC cherche à améliorer les rapports sur le rendement de la fiabilité du GADS
août 26, 2021
En vertu de la loi habilitante qui a créé l’Electric Reliability Organization, la NERC est responsable d’évaluer le rendement fiable du réseau électrique. L’une des façons dont la NERC le fait est d’obtenir un système de rapports de l’industrie pour la production et le transport. Le Système de données sur la disponibilité des générateurs (GADS) est utilisé par la NERC et l’industrie depuis plus de 40 ans pour obtenir des données sur la composante de production du système électrique[1]. En raison de l’évolution rapide de la composition des ressources de production, il est essentiel que NERC dispose de données complètes sur les installations, les événements, les pannes et les performances pour la production photovoltaïque et éolienne afin d’assurer la fiabilité. À mesure que les technologies renouvelables sont de plus en plus déployées, un ensemble complet de statistiques sur le rendement des actifs de production est nécessaire pour permettre à la NERC d’évaluer la capacité du système à répondre à la charge, la performance du réseau électrique et de prévoir tout problème de fiabilité potentiel en raison de l’insuffisance des ressources. Par conséquent, la NERC propose d’apporter les améliorations suivantes au processus de collecte de données GADS pour la production d’énergie renouvelable : Ajouter les propriétaires de générateurs qui exploitent des installations solaires photovoltaïques de 20 MW ou plus au Système de données sur la disponibilité de la production (appelé « GADS-PV ») ; et Élargir les rapports GADS Wind (« GADS-W ») pour inclure le stockage d’énergie connectée et le rapport d’événements.

NERC Addresses Single Points of Failure in Protection Systems Among Other FERC Concerns
octobre 25, 2018
Under the proposed NERC TPL-001-5 standard, utilities with transmission planning responsibilities will be required to identify reliability risks related to protection system failures and take mandatory corrective action. It will be critical to have an in depth understanding of your company’s protection system settings and to perform the system studies necessary to identify where single points of failure may result in cascading tripping of transmission elements. Mitigation actions may require the installation of redundant protection systems which in turn may lead to significant substation redesign. Transmission planners and planning coordinators should begin preparing for any necessary protection system changes. TPL-001-5 Overview NERC began studying the reliability risk associated with single points of protection system failure starting in 2011 as directed in FERC Order 754. TPL-001-5 will bring significant changes for Planning Coordinators and Transmission Planners as they perform annual Planning Assessments. There is a new obligation to adequately account for the reliability risk posed by single point of protection system failure via risk-based Assessment. This reliability risk management approach will be implemented through modifications to the Category P5 Planning Event which is described in Table 1 of the TPL-001-5 standard. NERC believes that the most cost-effective Corrective Action Plans to address unacceptable system performance for the P5 Planning Events will likely be to add protection system component redundancy in certain cases. Protection system redundancy changes to address Category P5 Event system performance violations should reduce or even negate non-redundant component related risks that need to be considered in assessing transmission system performance. These risks will be identified during simulations of certain extreme events as required under the standard. TPL-001-5 also addresses reliability risks related to outage management as directed in FERC Order 786. The standard requires utility planners to consider maintenance outages of significant facilities as well as outages for critical long lead time to repair or replace equipment. Specifically, it addresses stability analysis to assess system performance for conditions expected during possible unavailability of long lead time equipment. Although it is not a NERC defined term, it is believed that a “spare equipment strategy will be sufficient to allow flexibility for utilities to conduct both steady state and stability analysis required by TPL-001-5. For example, a utility’s spare equipment strategy may include the warehousing of a replacement transformer to be installed given the failure of an in service transformer. When a utility’s spare equipment strategy may prevent major transmission equipment from being out-of-service for one year or more, this possible equipment unavailability need not be assessed as part of TPL-001-5.
NERC Proposes Compliance Monitoring and Enforcement Plan for 2019
