+Why So Much Focus on Energy?
Rapid depletion of fossil fuels during the past 100 years, from accumulations of fossils during the past hundreds of millions of years.
Negative impact of burning fossil fuels on the environment – global warming.
2
+How Did This Arise?
Engineering inventions, and advances in science and technology during the 20th century have transformed society into one with intense and pervasive use of electrical energy.

+Consequences of Our Modern Way of Living
Electrification led to other great engineering achievements.
Each of the 19 other achievements is closely coupled to the availability of electricity. Each implies greater use of energy.
8
+Consequences of Our Modern Way of Living
The total energy demanded by the technologically transformed world can not be met without the availability of high energy density fossil fuels (coal and oil).
9
+Consequences of Our Modern Way of Living
Continued high rate of burning of fossil fuels using current technologies releases carbon dioxide and other gases, contributing to global warming, and placing earth and humanity at great risk.

+What is Game Theory?
Game Theory is a body of knowledge concerning decision-making in a system with two or more Decision Makers.
A player is a decision maker or a controller.
A player chooses a decision, strategy, or control.
A decision choice is based on available information.
Associated with each player is a cost or pay-off function.
A cost depends on one or more decisions.
Much of game theory deals with how a player selects a decision.
18
+Very Brief History of Game Theory Mathematical foundation of game theory:
John von Neumann and O. Morgenstern, Theory of Games and Economic Behavior, Princeton University Press, 1944 [1].
Game theory cuts across multiple disciplines of mathematics, operations research, economics, political science, control theory, and engineering.
For a recent brief history see
Jose B. Cruz, Jr. and Xiaohuan Tan, Dynamic Noncooperative Game Models for Deregulated Electricity Markets, Nova Publishers, 2009 [2,Section 2.1].
19
+Different Solution Concepts in Game Theory Players are assumed to be rational.
Zero-sum, min-max, max-min: Pure strategies (deterministic choice) Mixed strategies (choice of random distribution)
Nash equilibrium for nonzero sum games.
Pareto optimality.
Stackelberg equilibrium.

+ For Energy Systems, What Game Concept Is Appropriate?
• The government is one of the DMs and it will be a dominant player.• The dynamic Stackelberg strategy (Leader-Follower) is appropriate.• The dominant player is the Leader and announces its sequence of strategies first.
22
+Static Stackelberg Game
• Let there be two players, Player 1 and Player 2. • ui is the decision variable of Player i, ui ∈Ui , i = 1, 2. • Ji (u1,u2 ) is the scalar cost function of Player i, i = 1, 2. • One player, called the Leader, declares its decision strategy first. • The other player is called the Follower. • H. von Stackelberg, The Theory of the Market Economy,Oxford University Press, English translated ed., 1952 [3].
23
+Static Stackelberg Game -2
• Reaction Set of Player 1: D1 = {(u1,u2 ) ∈U1 ×U2 : T: U2 →U1, u1 = Tu2, J1(Tu2,u2 ) ≤ J1(u1,u2 ) for all u1 ∈U1, for each u2 ∈U2 }. • Stackelberg strategy pair with Player 2 as Leader, Player 1 as Follower: (u1S2,u2S2 ) ∈{(u1S2,u2S2 ) ∈D1 : J2(u1S2,u2S2 ) ≤ J2(u1,u2 ) for all (u1,u2 ) ∈D1}. • Similarly Player 1 may be the Leader and Player 2 the Follower.

+Dynamic Games
The evolution of a discrete-time dynamic system is modeled by difference equations x(k +1) = f (x(k),u1(k),u2(k),k), where x(k) is the state vector, ui (k) is the control or decision vector of Player i, and k is discrete time or time stage, k = 0,1, 2,...,N, and f is a mapping from x, u1, u2, and t to the space of x. The sequence {x(k)} describes the evolution of the state as a consequence of the application of decisions u1, u2 applied at preceding time stages. A continuous time model is described by a set of ordinary differential equations x = f (x(t),u1(t),u2(t)), t ∈[t0,tf ], x(t0 ) = x0 and the symbols are defined similarly. An open loop control is a time sequenceui = {ui (0),ui (1),...,ui (N −1)}, starting at a given state x(0) = x0.A closed loop control is a sequence{ui (k,x(k))} = {ui (0,x(0)),ui (1,x(1)),...,ui ((N −1),x(N −1))}.

27
+Dynamic Stackelberg Games
• A player, say Player 2, called the Leader, commits to a strategyfor the entire horizon of the game and announces it before the start of the game.• The other player, Player 1, called the Follower is aware of the Leader's commitment and as a rationale decision maker proceeds to optimize its cost function J1(u
1,u2 ) with respect to its choice for a
control sequence u1, taking into account the Leader's commitmnt to a specific control sequence u2.• The Leader notes how the Follower will react, and chooses u2 to optimize J2(u1,u2 ) under the condition that u1 is a reaction to u2.
28
+Dynamic Stackelberg Games - 2
• Define the reaction set of the Follower as the set of of u1 sequence for each possible announced commitment of u2 sequence by the Leader:R1 = {(u1,u2 ) : J1(u
1,u2 ) ≤ J1(v1,u2 ) for all v1 ∈U1 and
for each u2 ∈U2 }• If Player 1 is the Leader a similar reaction set for the Follower is defined:R2 = {(u1,u2 ) : J2(u1,u2 ) ≤ J2(u1,v 2 ) for all v 2 ∈U2 and
for each u1 ∈U1}• The Leader selects its decision from the reaction set of the Follower that results in the minimum of its cost function. 29

+Determining a Stackelberg Closed Loop Strategy At the initial state x = 1, each Player chooses a decision of 0 or 1.
At time 1, state x = 2, each player chooses a decision of 0 or 1.
At time 1, state x = 1, each player chooses a decision of 0 or 1.
At time 1, state x = 0, each player chooses a decision of 0 or 1.
Each decision maker or Player has 16 choices

For example, for u2 = c26 (0,1,0,1) Player 1 minimizes J1 and
gets u1 = c14,(0, 0, 1 ,1). This is repeated for each u2 = c2 j ,

+Stackelberg Example
There are two closed loop Stackelberg controls with Player 2 as Leader, (c15, c211) and (c16, c212 ), both leading to J1S2
c = 7 and
J2S2c = 2 and to the same trajectory x(1) = 2 and x(2) = 1. At time
t = 1, the remaining controls are (u1,u2 ) = (1,0) and the remaining costs are J1 = 2 and J2 = 5. Supose that Player 2 considers violating its commitment made at time t = 0 regarding its control at time t = 1. Its closed loop Stackelberg strategy for a game starting at t = 1 and x(1) = 2 is (u1,u2 ) = (0,1) leading to J1 = 6 andJ2 = 3. It will be tempted to violate its commitment to reduce its cost.
35
+Stackelberg Example -2
This example shows that the closed loop Stackelberg strategy violates Bellman’s principle of optimality. That is, the continuation of a previously announced closed loop strategy, starting at a later time, is not necessarily a closed loop Stackelberg strategy for a new game starting at the later time.
This example is in Simaan and Cruz [Ref 9].
36
+ Stackelberg Example -3
For the same example in [9] it was shown that the open loop strategy for a game starting at t=0, x=1 violates the principle of optimality.
If a Leader violates its commitment made at an earlier time and changes its strategy at a later time with a new commitment, there will be a credibility problem. The Follower may not believe a subsequent commitment by the Leader.
37
+Stackelberg Example - 4 This violation of the principle of optimality is known as time-inconsistency in economics.
The credibility problem and the time-inconsistency problem suggest that a Stackelberg-like closed loop strategy that satisfies the principle of optimality would be an acceptable suboptimal alternative.
Such a strategy, called Feedback Stackelberg was introduced in [7], precisely defined and fully described in [9]. It is a suboptimal closed loop Stackelberg-like strategy. But it is time-consistent.
38
+Feedback Stackelberg Strategies Principal property: The principle of optimality holds. (Time-consistency holds).
Dynamic programming can be applied.
Optimal Cost-to-go at stage k is the sum of the incremental cost at stage k plus the optimal cost-to-go at the next stage k+1, where the optimization is performed stage by stage starting with the last stage, in the sense of Stackelberg.
39
+ Dynamic Stackelberg Strategies
Feedback Stackelberg strategies proposed for the first time in Simaan and Cruz 1973 are suboptimal but time-consistent and widely used in macroeconomics. The same methodology can be applied to energy systems.
40
+Dynamic Stackelberg Strategies Are Pervasive in Macroeconomics
Kydland and Prescott published a paper in 1977 showing that the government strategy is time-inconsistent (violates the principle of optimality of Bellman’s Dynamic Programming). This paper revolutionized the entire field of macroeconomics.
Kydland published a more theoretical paper in 1975, used as a reference in Kydland and Prescott, 1977).
41
+Dynamic Stackelberg Strategies Are Pervasive in Macroeconomics
Kydland and Prescott won the Nobel prize in economics in 2004.
Kydland, 1975 referred to Simaan and Cruz, 1973, where time-inconsistency is proved. Simaan and Cruz, 1973 is a reference in Kydland’s Ph.D. dissertation supervised by Prescott at Carnegie Mellon University in 1974.
42
+Related Developments in Economics 12. Finn Kydland, “Equilibrium Solutions in Dynamic
Dominant Player Models,” Journal of Economic Theory, 15, 307-325, 1977. Kydland states that the dominant solution, open loop or closed loop are time-inconsistent. Suggests that a feedback solution is self-enforcing. Cites Simaan and Cruz [8,9].
13. Guido Taballini, “Finn Kydland and Edward Prescott’s Contribution to the Theory of Macroeconomic Policy,” Scand. J. of Economics, 107(20), 203-216, 2005. Taballini notes that Kydland [12] cites Simaan and Cruz [8,9].

Cites Simaan and Cruz: “The dominant player problem, on the other hand, has only recently received a little attention in the game literature, and the two interesting papers by Simaan and Cruz [24,25] should be mentioned.”

Motivating Case In the Philippines, Jatropha curcas has been touted as a promising dedicated energy crop for biodiesel production
However, investments in upstream (farm-level) production capacity has not been matched by corresponding growth in downstream (oilseed pressing and conversion) capacity

The Basic Model (Cruz et al., 2009)
Axt = yt

A = technical coefficient matrix
xt = sectoral total output vector at t
yt = sectoral net output vector at t
B = influence matrix

Presented at the 29th APAMS, July 13 - 15, 2009
Key Assumptions Matrix A reflects scale-invariant physical relationships such as process yields
Matrix B reflects econometrically determined collective behavioral responses of supply chain agents
Vector x reflects total system outputs, including intermediates
Vector actual y reflects net system outputs, while z gives the desired output level.
Production capacities are assumed to respond to surpluses or deficits incurred in the previous time interval.

The Basic Model (Cruz et al., 2009)
xt+1 = (I – BA)xt + Bzt
zt = Kxt + zo
where:
K = control matrix
zo = baseline target output
xt+1 = (I – BA + BK)xt + Bzo
(I – BA) defines the dynamic characteristics of the system.
Adaptive target output level is introduced
(I – BA + BK) now defines the dynamic characteristics of the controlled system.

Key Implications
Undesirable dynamic characteristics in nascent energy supply chains may arise due to feedback loops in physical linkages or information flows.
Control theory can be used to systematically design interventions to suppress undesirable system behavior.
Such interventions can come in the form of policy instruments or economic incentives/disincentives.

Presented at the 29th APAMS, July 13 - 15, 2009
Conclusions
We have extended our dynamic input-output model for nascent energy supply chains to incorporate weighted time lags in the capacity response.
This extension allows for added flexibility in modeling real systems wherein changes in production capacity may be subject to time delays.
