Experimentation of a Monitoring and control system for managing vulnerabilities of the European Infrastructure for Electrical power exchange

Objective

Vulnerability of the European Power System (EPS) is expected to largely increase due to the current trend to restructuring the electrical sector to a market-based environment, which is currently affecting all European countries. This shall widely increase the system volatility and put more stress on the transmission grid due to increase of cross-border energy trade, while utilities are forced to operate the system closer to the limit, so as to remain competitive. The EPS, which is composed of a set of interconnected national grids each one separately controlled by a national operator, is now extended to East European and Mediterranean countries, hence it is of strategic importance to control all possible disturbances so as to avoid their propagation. This project is to develop a novel monitoring system supporting EPS Control Centres, so as to test automatic control schemes in the context of highly disturbed conditions.

This project is to develop a novel monitoring system supporting EPS Control Centres, so as to test automatic control schemes in the context of highly disturbed conditions.

OBJECTIVES
Examine will develop information technology to improve the security of the EPS, so as to establish the basis for a real time control strategy to be adopted European wide. To this aim, Examine will design, prototype and test a novel monitoring system supporting the EPS control centres;
this system will allow to develop and test automatic control schemes in the context of highly disturbed conditions, so as to avoid large scale interruptions of service. The final objective is to maintain current security standards of national electric systems (related to continuity and quality of power supply) in the future scenario of a fully interconnected European electric grid with heavy loaded transmission lines. The field test will be done with the cooperation of the System Operators that support the project.The payback of the project will be obtained by allowing more freedom to the electricity market maintaining the security of the EPS.

DESCRIPTION OF WORK
Examine project offers a coherent approach to provide the expected scientific, technical and economical results to most of the needs unanimously expressed by all the European ISOs to improve grid emergency technology. The technical work plan of Examine has been divided into the three main phases:1. Examine emergency needs of the new deregulated European Power System: Starting from the available state of the art and the current knowledge of the Examine partners (ISO, research centre) new user needs will be expressed in the workpackage(WP2) to address reliability, security, and safety of the new deregulated European Power System. EXaMINE emergency needs will be expressed at the preventive, information processing and decision making levels.2. EXaMINE prototypes specification, integration and installation: From these EXaMINE emergency needs defined in WP2, EXaMINE consortium will focus on the specification, the development, and the integration of an EXaMINE prototype which integrates:
-Operator assistance tools to operate the Power System in preventive mode,
-New emergency control schemes. Prototypes specifications will be perform in WP3, prototype development, integration and installation in WP4.3. EXaMINE prototype experimentation and evaluation: Therefore, it will be time to experiment and evaluate EXaMINE prototype.The dissemination and exploitation parts of the EXaMINE workplan will be fully developed during the project and will become the most relevant workpackage of the project.
Main progress achieved: At the algorithmic level:
-Detailed needs expression and risk analysis.-Development of improved versions of emergency mode algorithms (voltage instability detection, contingency identification and location, transient instability detection and control, reinforcement learning based design of closed loop control systems).
-Implementation of fully operational prototype of the preventive mode algorithms.
-Realization of laboratory tests of the emergency mode algorithms.
- Realization of laboratory and field tests of the preventive mode algorithms. At the data acquisition and transmission level:
- Detailed needs expression and risk analysis.
- Analysis of dependability and security of various solutions.
-Proposal of different system architectures compatible with the needs expression.
- Development of phasor measurement placement strategies
-Development of a methodology to estimate mechanical state of generators from phasor measurements.
-Performance evaluation and tests of phasor measurement equipment. At the overall system level:
- Needs expression, risk analysis and functional specification of the EXaMINE system.
-Analysis of the hypothetical EXaMINE system dependability. Recommendations for further research and developments: At the algorithmic level:
- Develop real-time versions of algorithms for emergency mode transient instability and voltage instability detection and control.
- Develop distributed and parallel versions of preventive mode security assessment tools (thermal and voltage security; dynamic security).
- Develop emergency mode detection and control algorithms to cope with cascading line tripping and long distance electric power oscillations. At the data acquisition and transmission level:
-Install in a part of the European EPS a sufficient number of phasor measurement devices and real-time ultra-fast SCADA together with not operating control algorithms.
- Install preventive mode system in various European TSO's control centres. At the overall system level:
- Carry out field tests of emergency mode algorithms (in open loop).
- Carry out an in depth dependability analysis of the whole EXaMINE system.
