This paper calculates the existing system reliability index and typical daily optimal load distribution, studies the optimization problem of the generator unit’s investment plan in the next ten years, and uses the minimum cost of the investment plan to establish a multi-objective planning model. Combined with the artificial bee colony algorithm. It also discusses the impact of a large number of renewable energy power generation access power systems on traditional power system planning, and proposes an experimental model to solve this problem.
Based on the system enumeration method of fault enumeration, enumerate all possible states of the system at each moment, consider the total cost of the system, increase the load demand constraint on the basis, and obtain the probability of occurrence of low-order faults. LOLP, EENS and power outage fees.
After the above analysis, after the fault order reaches 5th order, the LOLP of the system is negligible, so the power loss cost is considered to be 4th order. Using the minimum total cost as the objective function, the artificial bee colony algorithm is used to find the optimal solution.
The uncertainty of the output of renewable energy in the power system greatly increases the risk of operation scheduling, does not guarantee the quality of power, and is currently economically poor. In view of the difficulties caused by the system components in solving nonlinear constrained power supply planning, an experimental model is also established.
