“RFE-NEC-DPRK-RK” POWER GRID INTERCONNECTION Sergei PodkovalnikovEnergy Systems Institute, Irkutsk, Russia

  • Introduction

  • Overview of NEC power system

  • Potential route

  • Preliminary costs-benefit analysis

  • Proposal for new scheme of the ISET

  • Inferences

2nd Workshop on PGI in NEA, May 6-8 2002, Shenzhen, China


Power Grid Map of Northeast China

2nd Workshop on PGI in NEA, May 6-8 2002, Shenzhen, China


Features of NEC Power System. I

  • Current generating capacity - 38 GW, electricity consumption - 154 TWh/year, frequency - 50 Hz

  • Maximum electric load comes in winter

  • Electricity consumption is unevenly distributed on the territory, with large share falling on South

  • Large share of generating capacity is located in South

  • There is currently excess of power generating capacity

2nd Workshop on PGI in NEA, May 6-8 2002, Shenzhen, China


Features of NEC Power System. II

  • Thermal power plants dominate in generation capacity mix

  • There is lack of maneuverable generating capacity for meeting cycling electric load of consumers

  • Backbone power transmission grid of highest voltage is developed

  • NEC power grid has local scale electric connection with RFE EPS

2nd Workshop on PGI in NEA, May 6-8 2002, Shenzhen, China


Benefits for NECfrom joining ‘RFE-DPRK-RK” power interconnection

  • Saving capacity at the cost of seasonal diversity power exchange with EPS of RK

  • Receiving maneuverable hydropower from DPRK

  • Getting profit from electricity trading with RK in seasons of low power loads of domestic consumers

  • Relieving environmental burden in season of highest winter loads at the cost of receiving power from RK

  • Increase of reliability and sharing reserve margin

2nd Workshop on PGI in NEA, May 6-8 2002, Shenzhen, China


Map of railroads of the South of RFE, NEC, DPRK and RK

2nd Workshop on PGI in NEA, May 6-8 2002, Shenzhen, China


The Scheme of «RFE-NEC-RK» Electric Tie

2nd Workshop on PGI in NEA, May 6-8 2002, Shenzhen, China


The Method of Study

Net Economic Benefit =

CostSavedCapacity - CostISET&Nuclear PP

Cost comprises annualized investment and yearly maintenance and fuel costs

2nd Workshop on PGI in NEA, May 6-8 2002, Shenzhen, China


Capacity and Investment Saving

2nd Workshop on PGI in NEA, May 6-8 2002, Shenzhen, China


Cost for “RFE-NEC-RK” ISET

2nd Workshop on PGI in NEA, May 6-8 2002, Shenzhen, China


Net Economic Benefit of “RFE-NEC-RK” ISET&Nuclear PP, $ Mln./year

The Scheme of «RFE-NEC-DPRK-RK» Electric Tie

2nd Workshop on PGI in NEA, May 6-8 2002, Shenzhen, China


The Method of Study

Net Profit =

Gross Benefits - Gross Costs

Gross Benefits - capacity saving, reduction of electricity tariffs and environmental benefit owing to power interconnection accumulated for 15 years

Gross Costs - cost for construction and maintenance of transmission and converters accumulated for 15 years

2nd Workshop on PGI in NEA, May 6-8 2002, Shenzhen, China


Economic Estimates of “RFE-NEC-DPRK-RK” ISET, $ Bln.

2nd Workshop on PGI in NEA, May 6-8 2002, Shenzhen, China


“RFE-DPRK-RK” ISET with “DPRK-NEC” Extension

2nd Workshop on PGI in NEA, May 6-8 2002, Shenzhen, China


Inferences

  • NEC joining to “RFE-DPRK-RK” power interconnection seems to be mutually beneficial for all participating countries.

  • There is quite developed transport and power grid infrastructure along the larger part of potential route of “RFE-NEC-DPRK-RK” ISET

  • As preliminary studies shows, the examined variants of the ISET ensure high economic benefits; such inference was drawn independently by both RK and Russian researches

  • It seems reasonable examining “RFE-DPRK-RK” ISET, with section “DPRK-NEC” being extended
