IEEE PES Croatia and IEEE PES Slovenia invite you to a
DISTINGUISED LECTURE by prof. Jovica Milanović titled:
Modelling and impact of distributed generation on system dynamics
The lecture will be held online on Wednesday, December 9th 2020 at 16:00 on MS TEAMS
Event will be held online, so the registration is not required.
The power systems at present are principally characterised with large and ever increasing presence of variable and intermittent converter connected renewable energy sources (RES). This will be even more the case with future power systems. They will be further characterised by blurred boundaries between transmission and distribution system, by mix of wide range of electricity generating technologies (conventional hydro, thermal, nuclear and power electronic interfaced stochastic and intermittent renewable generation), responsive and highly flexible, typically power electronics interfaced, demand and storage with significant temporal and spatial uncertainty, proliferation of power electronics (HVDC, FACTS devices and new types of load devices) and significantly higher reliance on the use of measurement data including global (Wide Area Monitoring) signals for system identification, characterization and control and Information and Communication Technology embedded within the power system network and its components. The integration of variable renewable generation, converter connected generation in particular, leads to conventional synchronous generators being displaced, hence the total inertia of the system will be reduced. This in turn affects system dynamic performance by: i) Changing the flows on major tie-lines, which may in turn affect damping of inter-area modes and transient stability margins; ii) Displacing large synchronous generators, which may in turn affect the mode shape, modal frequency, and damping of electromechanical modes of rotor oscillations; iii) Influencing/affecting the damping torque of nearby synchronous generators, similar to the manner in which flexible ac transmission (FACTS) devices influence damping (reflected in changes in the damping of modes that involve those synchronous generators); iv) Displacing synchronous generators that have crucial power system stabilizers. In order to successfully control such complex system its parts and components and to ensure its stability and security at acceptable cost, the system modelling and analysis need to cater for significantly increased uncertainties, both in terms of model uncertainties and operational uncertainties, and for efficient knowledge extraction from large amount of data coming from different types of local and wide area distributed data acquisition devices and monitors. This presentation focuses on new approach to modelling of RES to meet the above challenges, the impact of RES on system dynamics and gives and discusses the examples of probabilistic stability studies of power systems with RES.
