4 Market Based Criteria 40 is used as planning criterion, the plan which minimizes the sum of weighted square errors between mean of LMP of load buses and average LMP of the network is selected as the final plan. Therefore, this criterion decreases price discrimination among load buses and hence provides a non-discriminatory environment for consumers. This criterion assigns greater weight to the buses which have greater load. Hence, this criterion tries to provide a nondiscriminatory environment for more loads. Since this criterion assigns weight zero to the buses that do not have load, it does not encourage competition among producers necessarily. 4.2.2.4 Weighting with Sum of Mean of Generation Power and Load The mean of sum of generation power and load at bus i is given by: with: Nr k 1 k k µ ( P = ( + ) g + P P ) g P i i, j d for i=1, 2,…, Nb (4.15) d i, j i N k gi di P ( P + ) ∑ r j= 1 µ mean of sum of generation power and load at bus i after adding plan k in MW If the weighted standard deviation of mean of LMP with the weight: k k w i ( Pg + P i d ) i = µ for i=1, 2,…, Nb (4.16) is used as planning criterion, the plan which minimizes the sum of weighted square errors between mean of LMP of each bus and average LMP of the network is selected as the final plan. Therefore, this criterion decreases price discrimination among all customers and hence provides a non-discriminatory competitive environment for them. This criterion assigns greater weight to the buses which have greater sum of load and generation. Hence, this criterion tries to provide a competitive environment for more loads and generations. 4.2.3 Load Payment Form the viewpoint of power consumers total payment for buying power, i.e. total generation receives plus total congestion cost, is important. Hence, average of total load payment can be used as a criterion for transmission expansion planning. Average of total load payment during the peak load of planning horizon after adding plan k is equal to: Nr Nb k 1 k k µ = ∑∑Pd lmp tlp i j i, j (4.17) N , r j= 1 i= 1
4 Market Based Criteria 41 with: k µ average of total load payment during the peak load of planning horizon after tlp adding plan k in $/hr This criterion, however, does not consider competition among customers. In the rest of this thesis “average load payment” is used instead of “average of total load payment”. 4.3 Transmission Expansion Costs Justification of costs is very important in competitive environments. Therefore expansion planning criteria must take into account transmission expansion costs. Transmission expansion cost is divided into investment and operation costs. In this section, the presented criteria are developed in order to consider transmission expansion costs. When a new plan is added to the network operation cost changes. Thus, transmission expansion planning criteria must consider operation costs. Average cost of running generators during the peak load of planning horizon after adding plan k is equal to: N Nr g k 1 k µ = ∑∑Pg C i j g (4.18) rgc N , i, j with: r j= 1 i= 1 k µ average cost of running generators after adding plan k in $/hr rgc C g i, j Ng bid of generator i in the jth iteration of Monte Carlo simulation in $/MWhr number of generators Average load curtailment cost during the peak load of planning horizon after adding plan k is equal to: Nr Nd k 1 k µ = ∑∑Pc C i j d (4.19) lcc N , i, j with: r j= 1 i= 1 k µ average load curtailment cost after adding plan k in $/hr lcc k P c i, j amount of curtailment of load i after adding the plan k in the jth iteration of max k Monte Carlo simulation in MW or ( P − P ) d i, j d i, j
