摘要: In the competitive electricity markets, allocation of among multi-markets for purchasers is worth concerning. Based on portfolio optimization theory in field financial risk, a novel optimal electricity-procurement model local distribution company (LDC) presented, which can synthetically consider risk and expected purchase cost. For purpose assessment, conditional value at (CVaR) implemented. This applied to determine efficient frontiers LDC three markets. Then it compared with mean-variance model. Simulation results demonstrate that proposed guarantee bear minimum CVaR within an acceptable procurement It provides effective way manage cost electricity-purchase decision.
