| Abstract: |
| In order to solve the problem of insufficient peak load regulation ability for power grid accessed with high proportion of renewable energy, an optimal control method of peak load regulation combined CSP(Concentrating Solar Power) and thermal power is proposed. The adjustable characteristics of CSP and the control feasibility of peak load regulation combined CSP and thermal power are analyzed, on this basis, an optimal control mode of peak load regulation combined CSP and thermal power is proposed for power grid accessed with high proportion of renewable energy. Furthermore, an optimal control method of peak load regulation combined CSP and thermal power is proposed with the minimum system blocked wind and solar power as its objective. Case simulation shows that the proposed control method can effectively improve system peak load regulation ability and reduce the blocked wind and solar power. |
