Modeling of Large Electrical Power System Development under Energy Market Conditions

Aim of this paper is to incorporate energy market principles in large power system modeling process. The paper describes application of zonal (regional) energy price formation algorithms and interaction of power systems on energy import/export issues. The developed methodology is implemented in LDM-TG (Latvian Dynamic Model – Transmission and Generation) information technology, which was created and is being improved by the Institute of Physical Energetics, Latvia. The information technology provides the opportunity to perform dynamic optimization of system development together with operational state calculations. The authors discuss the possibilities to optimize long-term sustainable development of large electric power systems under energy market conditions

Model for Evaluation of Large-Scale Power System Interconnection Costs and Benefits

This paper considers the analysis of large-scale power system optimal interconnection concept as well as description of the model for evaluation of its costs and benefits. All existing power systems are willing to connect with other power systems. Power systems of one country merge together, countries developing interconnections and power systems of whole regions are constantly growing up. Developing new bigger power system from several small systems is slow process, but interconnected system has several big advantages – higher stability; higher reliability of power supply, especially in accident situations; better opportunities for optimal allocation of power reserves; better opportunities for optimal utilization of fuel and generation power. This paper contains the method for comparison different scenarios of interconnection of two world largest power systems - ENTSO-E and IPS/UPS by economical criteria. The research has shown that developed model helps to make deep analysis and is ready for calculation of interconnection links optimal locations, transmission capacities and interconnection type

Tasks of Transmission Planning in Competitive Energy Market

The main objective of this paper is to show the ways of improving electricity generation and transmission long-term planning methods. Paper reveals differences in approach to long-term planning in different market organization models, showing similarities and differences in tasks and procedures. Performing of some procedures is a complicated task, which requires creation of special computer models of interconnected systems. There is given a small test case, providing model for justification of building real interstate link – “LitPol”. Since the calculations are simplified and the results might be inaccurate, there are given only a review of the method. The model is developed using newest development of Laboratory of Power System Mathematical Modelling - PSPlanner software that also is going to be briefly presented

Approach to Modeling of Wind Power Plants in Long-Term Planning Tasks

This paper presents an approach to modeling of wind power plants in electric power system long-term planning tasks. There are shown the results of analysis of real wind power plant production curves from two small European power systems, performed in order to identify annual energy production and distribution of different groups of capacity values. Further, the paper reveals a method for modeling of imaginary production curves, based on obtained results. The paper also shows the way of generating simplified production curves that meet the requirements of long-term planning tasks, including modeling of several wind power plant parallel operation

Phasor Measurement Units Application in Frame of Interconnection of Large-Scale Power Systems

This paper contains the analysis of existing, as well as possible future application of Phasor Measurement Units (PMU) in frame of interconnection of large-scale power systems. The work is based on the real example – interconnection between EU and Russian power systems. The paper reviews the technical specification of PMU, data concentrators and information output instruments as modern dynamic monitoring system for power grid. The analysis have shown, that application of PMU in power system nodes gives a better opportunity to observe power system’s state, to make optimal decision on planning or protection measures, to perform a forecast, to choose optimal management scheme etc

Darbā ir paradīts, kāpēc netālajā nākotnē Baltijas valstu energosistēmai būs nepieciešamas jaunas lielas jaudas enerģijas avoti, un kāpēc ir jāizvērtē atomelektrostacijas kā vienu no variantiem bāzes jaudas deficīta segšanai

Sustainable Development Evaluation of Latvian Electrical Transmission Network and Generation

In paper are analyzed development conditions of Latvian power system, as well as selected the optimal sustainable development methods and technologies. In the paper it is described: 1) the transmission network and generation system development model; 2) results of Latvian power system development analysis till 2050. Research shown, that taking into account development conditions of Latvian power system, in nearest future, especially after Ignalina NPP closing, we will have base power capacity deficit. Therefore, the topical problems are related to new power plant construction, transmission network reconstruction taking into account liberalized electricity market conditions. One of possible ways of solving this problem is building modern nuclear power plants
