1 Cigre SC B4 Activities Towards HVDC Grids Bjarne Andersen Chairman of Cigre Study Committee B4 HVDC and Power Electronics HVDC Grid Workshop Belgium
2 Contents Why build HVDC Grids? Types of HVDC Grids Issues to be faced SC B4 s Work in the area of HVDC Grids Interactions between AC grid and HVDC Grid Elecrama, Bengaluru, HVDC Grid Workshop Belgium
3 HVDC Systems Almost all HVDC systems are point to point schemes (OHL, cables or BtB). Two multi-terminal HVDC schemes with three terminals are in service. A further scheme is in construction in India North East to Agra, 800kVdc, 6000MW. Why not more multi-terminal schemes? LCC technology will suffer commutation failures for large ac network disturbances at the inverter terminal, resulting in brief interruption of power flow ( about 100ms). Power reversal for LCC HVDC schemes requires a dc voltage reversal so some stations may need full HVDC withstand of both ends of each converter arm. Whilst VSC HVDC does not suffer from commutation failures and do not require voltage reversal when power reverses, VSC HVDC technology is relatively new. HVDC Grid Workshop Belgium
4 HVDC Grids Because of the growing number of HVDC schemes and with many of the terminals for these placed in close proximity the idea of a HVDC Grid was born. Point to Point HVDC HVDC Grid An HVDC Grid is defined in Cigre as an HVDC system consisting of at least three converter stations and at least one mesh formed by transmission lines. HVDC Grid Workshop Belgium
5 HVDC Grids Cigre WG B4.52 studied the feasibility of HVDC Grids, Technical Brochure No 533, concludes: There are no insurmountable technical obstacles to building HVDC Grids. Issues to be resolved includes The protection of the HVDC Grid. Functional control strategies for the HVDC Grid. Development of Central Co-ordinating Controllers. Development of modelling tools and generic converter models. The selection of a set of preferred DC Voltages for HVDC grids. The development of Grid codes for HVDC Grids. The development of benchmark tests for additional converter stations. The development of efficient DC/DC converters. HVDC Grid Workshop Belgium
6 HVDC Grids Several HVDC Grids have been proposed and are being investigated in Europe. The purpose of all of these is to increase the amount of renewable energy that can be accommodated in the overall energy system. Projects include: The European SuperGrid The North Sea Grid The MedGrid Desertec HVDC Grid Workshop Belgium
7 Challenges of a HVDC Grid TB 533 identifies that the building of meshed HVDC Grids will result in a number of technical challenges. Examples of issues that have to be resolved include: The protection of the HVDC Grid. Functional control strategies for the HVDC Grid. Development of Central Co-ordinating Controllers. Development of modelling tools and generic converter models. The selection of a set of preferred DC Voltages for HVDC grids. The development of Grid codes for HVDC Grids. The development of benchmark tests for additional converter stations. The development of efficient DC/DC converters. HVDC Grid Workshop Belgium
8 Types of HVDC grids Converter Design VSC or LCC? Both are potentially possible Converter arrangement Bipolar, Monopolar, Balanced Monopolar, or a mixture? This is a decision to be taken by the HVDC Grid Developer Earth Return Arrangements provided or not? The earthing strategy depends on the converter arrangement. It has a major impact on the performance during faults to ground within the HVDC Grid. Converter Topology Full Bridge or Half Bridge? Both can be used, and the optimum solution may be decided based on functional requirements. HVDC Grid Workshop Belgium
9 SC B4 WGs in the area of HVDC Grids WG B Guidelines for the preparation of connection agreements or Grid Codes for HVDC grids. WG B Guide for the development of models for HVDC converters in a HVDC grid. WG B Devices for load flow control and methodologies for direct voltage control in a meshed HVDC Grid. JWG B4/B Control and Protection of HVDC Grids. WG B Designing HVDC Grids for Optimal Reliability and Availability performance. JWG B4/C1.65: Recommended voltages for HVDC grids. JWG A3/B4.34: Technical requirements and specifications of state-of- the-art DC Switching Equipment. HVDC Grid Workshop Belgium
10 WG B Guidelines for Grid Codes for HVDC grids. The TB will provide guidelines for the studies and documents necessary to prepare the following activities: The grid development plan of a power system including HVDC Grid; The technical specifications of a HVDC Grid control and protection system e.g. functional characteristics and settings; The technical performances of a HVDC Grid guaranteed to its users, e.g. steady state and dynamic dc voltage range, ; The technical requirements for new equipment to be connected to a HVDC Grid, including insulation and control and protection specifications; The requirements for the connection, testing and operation of new equipment to be connected to a HVDC Grid; The specifications of the data to be exchanged between individual equipment and the HVDC Grid central co-ordination control system. The WG is expecting to complete its activities in 2014 HVDC Grid Workshop Belgium
11 Temporary DC Voltage Limits Limit 1, 2: Limit 3: Limit 4a, 4b, 5: Limit 6: Limit 7, 8: Insulation Coordination Study Protection Coordination Study Overvoltage Study, Dynamic Performance Study Protection Coordination Study Load Flow Study HVDC Grid Workshop Belgium
12 WG B Models for converters in a HVDC grid. Modelling of the HVDC Grid and its converters and components, and studies using these models are an essential part of the planning of an HVDC Grid. Models will be needed for steady state dynamic and transient studies. Thus Phasor and EMT models will be discussed. It is recommended that models be separated into upper and lower level controls. These upper level controls are independent of the PE topology. The lower level controls system is very dependent on the PE topology. Models will need to be provided by different manufacturers, who will want to protect their IPR. The WG will be covering the protection of IPR. An HVDC Grid test system has been developed jointly with B4.58. The test system will be used by all WGs for their studies. Academics and researchers in HVDC grids are encouraged to use the test system. HVDC Grid Workshop Belgium

15 WG B Load flow control devices and dc voltage control methodologies DC Voltage control in a HVDC Grid is critical and must be fast, because of relatively low energy storage. Various dc voltage control strategy are being considered, with dead bands and the duty shared using droop controls. The branch power flow depends on the voltage difference across the branch, and the branch resistance. It is not possible to control all branch power flows. Branch power can also be controlled by insertion of resistance (power loss) or DC/DC converters. The WG is examining different types of DC/DC converters HVDC Grid Workshop Belgium

19 JWG B4/B Control and Protection of HVDC Grids Similar to an AC network selective, fast and reliable protection is key to good performance and high availability of an HVDC Grid. The protection of the converter station equipment is likely to remain unchanged. Typical Voltage Sourced Converters turn into a diode rectifier during faults on the dc side. Therefore dc side fault current can become very high. Cable section in the HVDC Grid can also contribute to high dc side fault currents. It is expected that faults on the dc side need to be cleared within 5ms, to prevent a collapse of the HVDC grid. This require power electronic devices. To reduce the power loss hybrid switches, including ultra fast mechanical switches may be used. Other alternatives are also being investigated. Alternative converter topologies, capable of blocking dc side fault currents, are being proposed for HVDC grids. Reactors may be used strategically within the grid to slow down the fault current increase, but result in additional power loss. HVDC Grid Workshop Belgium
20 Short Circuit in HVDC Grid HVDC Grid Workshop Belgium
21 WG B Designing HVDC Grids for Optimal R&A performance HVDC Grid Reliability and Availability concepts will be quite different from those considered for point to point HVDC schemes. The WG will propose criteria derived from those used for ac networks. This WG is reviewing the impact on R&A of different HVDC Grid and converter topologies. Operating strategies, including spares holdings and maintenance is being considered. The impact of HVDC Grid protection strategies is being considered. The impact of converter and line outages is being considered. HVDC Grid Workshop Belgium

23 Other WGs in the area of HVDC Grids JWG B4/C1.65: Recommended voltages for HVDC grids. This JWG was established in It is considering only the pole to pole and pole to ground dc voltage. Recommended voltages may benefit HVDC developers wanting to future proof their investment. However, when it is unlikely that a scheme would become part of an HVDC Grid, the optimum dc voltage, and not the preferred dc voltage should be used. The JWG is expected to complete its work in JWG A3/B4.34: Technical requirements and specifications of state-of-the-art DC Switching Equipment. The JWG was established in It will look at the mechanical parts of the dc side switchgear, including isolators, disconnectors, earth switches, and fast dc load switches and ultra fast dc circuit breakers. HVDC Grid Workshop Belgium
24 Interaction between AC Grid and HVDC Grids Faults in either Grid will impact on the other. Both Grids have the potential to assist the other during emergency conditions. Planning and Dynamic Studies will need to be performed to determine: Redundancy/Reinforcement Requirements for either Grid Protection Requirements Functional Control Requirements for steady state, dynamic and emergency conditions HVDC Grid Workshop Belgium
25 Will HVDC Grids be Implemented? There is high political interest in Europe. The drivers are increasing amounts of renewable energy, the need for more transmission capacity, but opposition to new OHL. Some of the issues delaying HVDC Grids include: The magnitude of the investment which will be needed whilst economies are only slowly emerging from a recession. Fragmented ownership of existing HVDC schemes. Uncertainty resulting from short term energy policies in many countries. Political issues associated as an HVDC Grid may cover many different countries, with different energy policies and security concerns. An HVDC grid has not yet been built, even though the technical experts agree that there would be no insurmountable difficulties. Building an HVDC grid requires a large amount of studies and decisions to be made by the developer. The Cigre work provides a good basis for this work, but does not provide the specific answers. Nevertheless, the Author believes that the building of HVDC Grids will commence within the next few decades. HVDC Grid Workshop Belgium
