Lecture 1: WIND energy integration in Low Inertia Power System
Igor Kuzle, Ph.D.
Increase in number of wind power plants that utilize variable speed generators that substitute conventional synchronous generators has led to a decrease in system inertia. This decreases system stability in response to disturbances that causes power swings (generator and load outages, short circuit failures). Renewable energy sources have potential capabilities to provide initial inertia response and ancillary services. In presentation will be presented the main goals, methods and overview of the WINDLIPS project.
Lecture 2: Dynamic thermal rating system in Croatian transmission power system
Krešimir Mesić
This article presents dynamic thermal rating system named SUMO, which has been developed in order to improve system security and enable optimal utilization of the existing power system infrastructure. A modern information system produces real time and close future estimations of actual thermal capacities. Currently, power systems mostly operate using static thermal capacity limits that have been determined considering constant values of atmospheric conditions. Project SUMO started in 2018 and it will be implemented on 220kV power lines. This article introduces SUMO system components and presents its scope of use.
Lecture 3: Advanced inter TSO Voltage-VAR Scheduler for coordinated voltage control
Marko Rekić
Voltage situations with extremely high voltages as well as highly volatile voltages mainly caused with integration of RES in the southeast European region are causing serious operational challenges in the Slovenian and Croatian transmission grids. In order to address those challenges ELES and HOPS have started a common SINCRO.GRID project. The project aim is to solve the problem of overvoltages and optimize operation in both grids in a coordinated and sustainable manner. It includes deployment of new voltage and reactive power control devices and implementation of a Virtual Cross-Border Control Centre (VCBCC) for their control. The main goal of the VCBCC project is bringing the voltage profile to a secure level allowing connection of more renewables, distributed generation and other critical users to the grid.
Lecture 4: Architecture of new Data Warehouse in HOPS
Tomislav Brejar
HOPS, the Croatian transmission system operator is in the process of migration to the new data warehouse system. The new advanced analytic platform, built on an IBM advanced analytic stack (IBM PureData System for Analytics, IBM InfoSphere DataStage, IBM Cognos Analytics and IBM SPSS) has improved key business parameters for HOPS by providing on-time, accurate data for managing the national transmission network. Some of the most complex reports can now be generated up to 100 times faster compared to the old analytics solution. This presentation will focus on the architecture of the new system. Additionally, overview of the presentation layer capabilities together with report examples will be presented.
Lecture 5: Energy storage optimization and ancillary services provision potential
Ninoslav Holjevac and Matija Zidar
The coordination between the Transmission System Operator (TSO) and the Distribution System Operator (DSO) is crucial for secure supply of electrical energy to all customers. In the environment where a lot of intermittent production is connected both in the DSO and TSO networks the balancing and flexibility requirements are on the increase. The different aspects of flexibility services provision from the distribution system level can greatly help to alleviate the potential problems even in the TSO network level. This talk will deal with the energy storage optimization process and will mention some aspects of ancillary services provision potential of the energy storage systems integrated in the DSO network.
