Market Based Criteria for Congestion Management and Transmission PricingIJERA Editor
Congestion Management is one of the major tasks performed by system operator to ensure the operation of transmission system within operating limits. In the emerging electric power market, the congestion management becomes extremely important and it can impose a barrier to the electricity trading. In the present paper, a concept of transmission congestion penalty factors is developed and implemented to control power overflows in transmission lines for congestion management. Here we presents a Re-dispatch methodology for cost of transmission network to its user. The transmission price computation considers the physical impact caused by the market agents in the transmission network. The paper includes case study for IEEE 5 bus power system.

Assessment of Market Power in Deregulated Electricity Market with CongestionIDES Editor
Restructuring of electrical market worldwide has
brought the issue of market competition to the forefront. This
new perspective has given rise to competition with the goal of
price fall and technological innovation in the sector. In the last
few years a great deal of attention is given to the possibility of
a group of producers (agents) exercising market power by means
of congestion effects. The possibility of two agents acting in a
combined way on the Transmission System affecting the
accessibility by the others to a specific Market is analyzed. This
paper describes an algorithm used to detect measure and
evaluate the impact of these kinds of strategic actions on market
concentration. The results obtained from the study using 9 bus
example network shows that this kind of actions can affect
strongly market share and must be predicted by the Independent
System Operator (ISO).

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

CHINA’S GEO-ECONOMIC OUTREACH IN CENTRAL ASIAN COUNTRIES AND FUTURE PROSPECTjpsjournal1
The rivalry between prominent international actors for dominance over Central Asia's hydrocarbon
reserves and the ancient silk trade route, along with China's diplomatic endeavours in the area, has been
referred to as the "New Great Game." This research centres on the power struggle, considering
geopolitical, geostrategic, and geoeconomic variables. Topics including trade, political hegemony, oil
politics, and conventional and nontraditional security are all explored and explained by the researcher.
Using Mackinder's Heartland, Spykman Rimland, and Hegemonic Stability theories, examines China's role
in Central Asia. This study adheres to the empirical epistemological method and has taken care of
objectivity. This study analyze primary and secondary research documents critically to elaborate role of
china’s geo economic outreach in central Asian countries and its future prospect. China is thriving in trade,
pipeline politics, and winning states, according to this study, thanks to important instruments like the
Shanghai Cooperation Organisation and the Belt and Road Economic Initiative. According to this study,
China is seeing significant success in commerce, pipeline politics, and gaining influence on other
governments. This success may be attributed to the effective utilisation of key tools such as the Shanghai
Cooperation Organisation and the Belt and Road Economic Initiative.

3. Present Power System
- Heavily Relying on Fossil
Fuels
- Generation follows load
- Limited ICT use
- Limited Competition
Future Power System
- More use of RES, clean
coal, nuclear power
- Load follows Generation
- More ICT & Smart meter
use
- More competition
4. Prior to the enactment of Electricity Act 2003 there was a
monopoly of government.
A single entity I.e. government was taking care of all
electricity business such as generation, transmission
and distribution.
Continued power shortages, poor operational
performance and precarious financial situation of SEBs.
6. After passing of Electricity Act 2003,the
competition came to the forefront, both
government and private companies have
jurisdiction over it.
De-licensing of thermal generation including
captive generation.
Non-discriminatory open access in transmission.
Deregulation comes into the picture
8. Deregulation is the process of removing or reducing state regulations. It is
therefore opposite of regulation, which refers to the process of the
government regulating certain activities.
The basic idea of restructuring includes introducing competitive energy
markets, unbundling electricity services and opening access to the network.
The objective of restructuring is to provide better options for industrial
contributors and to introduce revolutions with improved quality service and
choice to the customers at economical prices
Energy prices are not regulated in these deregulated areas and consumers
are not forced to receive supply from their utility.
9. Deregulation allows competitive energy suppliers to enter the
markets
Deregulation gives consumers choice - the power of the buyer. A
deregulated market allows you to choose your commodity supplier.
Restructuring comprises different activities; changing existing
companies corporation, privatization and dissociation
12. With the introduction of restructuring into the electric
power industry, the price of electricity has become the
focus of all activities in the power market.
The objective of transmission pricing is to recover all or
part of the existing and new cost of transmission system.
13. The pricing of the transmission service must meet the
following requirements:
Promote economic efficiency.
Compensate grid companies fairly for providing
transmission services.
Allocate transmission cost reasonably among all
transmission users.
Maintain the reliability of transmission grid.
14. EXAMPLE
◦ Let genenerator-1 has capacity of 100 MW with production
cost $75/MW per unit time. Demand is 100 MW. Bid of other
gen at the same bus is
What should be bid of gen-1?
Option-1: bid at 100 $/MW
◦ win all demand of 100 MW. The profit will be 100(100-75)= 2500
Option-2: bid at 120 $MW
◦ win 50 MW capacity. The profit will be 50(120-75)= 2250
This shows the option-1 is preferred.
If second block of other gen. is 131 $/MW. Profit at bid price of
130 will be 50(130-75) = 2750.
◦ Now this is preferred.
50 MW 101 $/MW
50 MW 121 $/MW
15. BIDDING STRATEGY IN ELECTRICITY MARKETS
Theoretically, in perfect electricity markets, suppliers should bid at or very
close to their marginal cost to maximize profit.
However, the electricity market is not perfectly competitive due to limited
number of producers, therefore, power suppliers may seek to benefit by bidding
a price higher than the marginal production cost.
When a supplier bids other than the marginal cost, to take advantages of
imperfect market to increase their profit, this behavior is called strategic
bidding.
The bidding strategy decision of an individual supplier can be affected by
demand variation, generator cost characteristic, rivals bidding behavior,
operating and regulatory constraints.
Each supplier developed bidding strategy to maximize their profit, considering
own costs and constraints, rivals' bidding behavior and market rules.
16. Transmission constraints restricts the flow of power from low
cost node to high value nodes.
Since transmission network capacity is limited, it may happen
necessary to select expensive bid to avoid transmission
overloading. Therefore, constraints on the system will cause
different prices at different nodes.
Revenue collected from the consumer will be more than the
money paid to the generators in uniform market clearing price
system.
The market based congestion management methods can be
categorized as:
Locational marginal price
Zonal price
Market split
Counter flow re-dispatch
BIDDING IN CONSTRAINED NETWORK
17. BIDDING STRATEGIES FORMULATIONS
1. Deterministic formulation
• Uncertainty are not included
• No temporalities
• All rivals are clubbed together
2. Stochastic formulation
•Uncertainty of bid price of
rivals
•Uncertainty of demand
•Temporalities are considered
•Rivals’ are not clubbed
Bidding problem formulation depends upon the market model, type of bidding
protocol, auction mechanism and estimation technique of rivals’ bidding behavior.
Solution approaches
1. Conventional methods
2. Heuristic approaches
18. Bidding is an offer (often competitive) of setting a
price one is willing to pay for something or a
demand that something be done. A price offer is
called a bid.
19. Buying or selling of energy takes place in
the form of bids
Bidding
20. • Agents submit bids (Quantity and cost) to either buy or sell
energy.
• Independent System Operator (ISO) matches the bids
21. • Bids below MCP are
accpeted
• Two types of payments
for bids
i) Uniform pricing
ii) Pay as bid
Strategic bidding:Aim is to construct best optimal bid knowing their
own costs, technical constraints and their expectation of rival and
market behavior
