Modelling the settlement effects of Project Energy Connect - Final Report

ACIL Allen shall not be liable in respect of any claim arising out of the failure of a client investment to perform to the advantage of the client or to the advantage of the client to the degree suggested or assumed in any advice or forecast given by ACIL Allen. [...] The shadow price of the loop flow constraint and the coefficients of the lines involved in the constraint now need to be included. [...] If the shadow price of the loop flow constraint is 𝜇 and the coefficient of line k in this constraint is 𝑑𝑘 then if we just model simple thermal steady state constraints the LMP of bus n is 𝐿𝑀𝑃𝑛 = 𝑅𝑅𝑃 + ∑ (𝜆𝑘 + 𝑑𝑘 × 𝜇) × 𝑐𝑘,𝑛 𝑘 𝑖𝑛 𝑛𝑒𝑡𝑤𝑜𝑟𝑘 𝑐𝑜𝑛𝑠𝑡𝑟𝑎𝑖𝑛𝑡𝑠 Note that if generator terms are added to the loop flow constraint instead of the coefficients of the lines th. [...] The model includes the following constraints to allow the solver to optimise the PST for the least cost solution. [...] This reflects the changing direction of the PST setting and the coefficient applied in the loop flow constraint, spreading flow around the loop.
