The load forecasting of DiscoZ on 10 May 2023 is equal to 400MW. However, on that day the actual demand is equal to 432MW. In a balancing market, the selling price is RM0.40/MW while its purchasing price is RM 0.20/MW. Calculate the cost DiscoZ needs to pay to the balancing market.

Predicted demand of a product for the current month = 4,064 unitsActual demand of the product for the current month = 4,806 unitsSmoothing constant = 0.2Required: Forecast the demand of the product (in units) for the next month?

In a bilateral market model, how much power is needed to buy/sell from the power  exchange company if the forecasting and actual demands are 350MW and 300MW, respectively

Consider an electricity market where the base of the demand curve is vertical and varieslinearly between 4000MW and 8000MW (so is equally likely to be found anywhere inthat range). Above 7500MW demand can be curtailed at a price of $4000/MWh. Themarket is competitive with three types of plants as below.Technology FC per MWh Variable costs perMWhCarbon Emissionsin tonnes perMWhPeak (diesel peaker) $18 $160 25Mid (gas) $35 $50 10Baseload (hydro) $55 $0 0(a)What is the optimal amount of baseload plant that should be built? (2 marks)(b) What is the duration of the price spike so that the peaker plant just recovers itsfixed costs? (2 marks)(c) What is the optimum mid-load capacity? (2 marks)(d) What is the total capacity and hence peak capacity? (2 marks)(e) Sketch the load duration curve and the offer stack (2 marks)(f) Show all plants just cover costs (4 marks)(g) Suppose now the government imposes a tax of $30 a tonne. Suppose there is nochange in capacity (so capacity doesn’t adjust). Calculate the profit that each type ofplant makes. Why do some plants make a profit even though the market iscompetitive?
