What is it about?
In this article, a Particle-Swarm-Optimization technique is used to find out the optimum combination of wind-tidal-PV generation size and location that maximizes the reliability of the system. In this case, the reliability is defined as the total energy-not-supplied, therefore, the optimum combination of renewables is the one that minimizes the energy not supplied such that electrical supply interruption duration and frequency are also minimum.

Why is it important?
In most cases, the deployment of renewable generation is evaluated in terms of total cost and return of the investment, as requested by the local utility. This allows the investors and manufacturers to propose large wind farms and extended PV areas that produce significant amount of power which is injected into the grid even at the distribution level, and some of it could be unexploited if not required. A different approach is to consider reliability as the design driver, which allows a certain combination of renewables to be complementary and maximize the use of its energy at all times.
